Creating Etherial Long Exposures With Breakthrough Photography’s X4 ND Filters

The Peace Of The Creative…

Slowing down creates peace on multiple levels.

For you as the photographer and for those who view your work, this has never been more true!

I am going to do a slightly different type of post this time.

We will discuss the art of Long Exposures a bit but we will focus more on the technical aspects of using ND filters to correct for different types of lighting as well as talk about good ND filter systems verses not so good, and why it is always best to invest your money in good filters!

Definition: Long Exposure – To create an image in camera with the shutter open for longer than a few seconds in order to smooth out movement over time. This can be softening the flow of water over a waterfall, flattening of waves in lakes and oceans or tearing clouds moving across the sky.

Setup: For camera setup you want a long shutter speed (for me usually from 20 seconds to 60 min), mid range aperture (f/16) and the base ISO that your camera provides. You do NOT want to switch on the L ISO in your camera. While it forces the ISO lower it costs you in reduced dynamic range! You should also verify that your camera has Long Exposure Noise Reduction turned on. This is a royal pain due to doubling of exposure time and forcing you to wait twice as long for a shot but it removes sensor generated noise as well as sensor hot spots.

Note: I have added a video to the bottom. It discusses everything and more that we are talking about in this post but it is quite long!

The top image was taken at the always inspiring Roanoke Marshes Lighthouse across the sound from Nags Head Island in NC. As one of my favorite locations for sunrises over the lighthouse it is also a most worthy location for daytime long exposures! These are usually very easy to create due to the small waves in the sound! This image was done on a Fuji GFX 50R medium format digital with a 32-64mm GF lens, 6 stops of ND (Breakthrough X4 magnetic) and a X4 2 stop soft graduated ND on the sky to balance the difference between the sky and water. The exposure was 20 seconds an hour after sunrise and in the rain.

But by what criteria did I choose the solid ND and the soft edge graduated ND? This is where a little technical knowledge will really help you in creation of amazing long exposures.

First, there are a few points to consider when thinking about using ND filters:

ND filters are simply sunglasses that you put in front of your lens to limit the amount of light that reaches the camera.
There are 2 basic styles of ND, Full and Graduated. Full covers and darkens light passing through the entire lens, Graduated cover and darken only part of the light passing through the lens with the ability to rotate the edge angle of the start line and moving the line up or down in the scene.
In the full family there are several values and styles.Breakthrough Magnetic lens mount with the rotating dial on the back to rotate the filter
- Screw on: they simply screw onto the end of your lens
- Magnetic: these are a new (2018) system from Breakthrough Photography. They require you to buy a special magnetic mount bracket for the filter threads on your lens. The adapter has a rotating ring that allows the filters to be actually turned (for use with polarizers) and costs about $20. Currently, Breakthrough is re-designing both the magnetic filters and the magnetic lens adapters to allow for stacked magnetic filters. This should be completed by summer 2019 and they will replace the older style magnetic filters and adapters. It is important to tell you that when you use the magnetic filter system alone or with the square system there is NO vignetting.
- Breakthrough Square holder that attaches to the magnetic adapter
- Square: these use a square holder and in the case of the Breakthrough this holder will attach directly to the magnetic holder allowing use of and stacking of both systems at once. The square holder will hold 3 to 5 filters depending upon how you initially set it up. This is good for difficult lighting situations where you might need two different graduated filters at the same time. This style tends to suffer from light leaks around the edges of the square solid ND filters unless you carefully assure that they are installed exactly right and only in the holder slot closest to the lens.

In the graduated family there are several types:Breakthrough Photography X4 soft Graduated 100mm filter system
- Hard edge graduated: where the dark area of the graduated filter is a sharp line. This is for use on subjects which have a harsh division between the foreground and background . An example would be shooting on the ocean where the horizon is a sharp line between the horizon and the sky. This is where you would choose a hard edge graduated ND. These filters usually come in 1, 2 and 3 stop values where they start light and graduate to the dark.
- Breakthrough reverse grad
- Soft edge graduated: where the dark edge of the graduated filter starts very soft and light and darkens as it moves up the filter. This is for use in areas that you need to balance the foreground from the background but there is no clearly defined edge in the scene. This is what I used in the image above to darken the sky so there was detail there and still enable the water foreground to be bright and almost a platinum look and feel. These filters usually come in 1, 2 and 3 stop values where they start light and graduate to the dark.
- REVERSE graduated: this is a special graduated ND where it starts DARK and graduates up to lighter values. If you desire to shoot sunrise/sunset this is a MUST have filter because as the sun approaches the horizon you get a very bright line of colors there that will either be blown out or if exposed correctly cause the rest of the image to be way too dark! These filters usually come in 1, 2 and 3 stop values where they start dark and graduate to the light.

So for the Roanoke Marshes Light above, I chose a Breakthrough magnetic X4 (newest technology) 6 stop solid nd to darken the entire image allowing for the 20 second exposure with the camera set to the lowest native ISO value (100), an aperture of f/16 and a shutter speed of 20 seconds. the initial results of this exposure was pleasing water in the foreground but the sky was also too light with little to no detail. So I left the 6 stop magnetic filter on the lens and clipped on the 100mm square filter adapter onto the end of the magnetic adapter and installed a X4 soft edge 2 stop SOFT graduated ND filter. While watching thru the viewfinder I adjusted the graduated ND up and down making sure that the soft edge came down to the horizon or a little above darkening the sky to allow for more detail there yet allowing the soft white water in the foreground! It was as simple as that! The entire process after the first shot took about 30 seconds to setup on the camera lens then shoot!

So let’s talk about sunrise/sunset images when the sun is close to the horizon. We have all been out at sunrise, do you remember the very bright band of intense color that it right at the horizon as the sun approaches? This is why the reverse grad ND filter was created, to keep the bright colors from destroying the overall exposure! Here is an example image, amazingly at the same spot!

Do you see how bright the light is at the horizon? The ONLY WAY I was able to capture this image was to use the reverse grad ND placing the dark section right on the bright band of light. Because the overall exposure was only 3 seconds no other ND filters were required. Should I have desired a longer exposure to further soften the water’s surface I would have dropped in the 3 or 6 stop X4 magnetic filter into the adapter already on the camera!

Let’s take a short side trip here and discuss the actual filters. By now you all have seen that I am a strong user and promoter of the Breakthrough Photography X4 line of magnetic and graduated filters. There is a reason for that:

All dark solid ND filters suffer from some sort of light leaks around the slide in filter holder. The magnetic mounted X4 Breakthrough filter line has solved this problem.
The X4 Breakthrough filters have ZERO COLOR CAST! This is a really big deal. I have been a big user of B+W and Lee filters over the years and still have them on hand. Unfortunately, both of those both have strong color casts that force me deeper into post processing to attempt to correct these color casts. I had always thought that this was simply the cost of doing long exposure! Well NO MORE! I am so pleased to report that those problems are not the case with Breakthrough, ALL BREAKTHROUGH filters! Cost wise they all cost about the same when you get up into the same quality levels (B+W, Lee, SinghRay and Breakthrough). So for me it was an easy choice, I have totally converted over to the Breakthrough X4 line of filters. I currently am using the magnetic and square system from them.
There is ZERO vignetting with the magnetic system on ANY of my lenses. I currently and using 72mm, 77mm and 82mm lenses and mounting both the magnetic system and the 100mm system together!
Breakthrough filters come with a 25 year guarantee and their customer service is crazy good. They are currently (Feb 2019) working on an updated magnetic system where the filters can be stacked in the holder!

So my advice is this. Cameras come and go, it is your glass (lenses and filters) where your quality lays. Invest in the best you can. You will never go wrong with the Breakthrough system! (gee I wish they would pay me…)

Ok, back to images. After sunrise is done and before sunset is anywhere near we can still create AMAZING long exposures! There only 2 problems that we must overcome!

Slowing down the shutter speed to give the long exposure. During normal daylight we will likely be using a 10 or 15 stop solid magnetic X4 ND as long as the sky and the foreground are near the same exposure value.
Should the sky be brighter than the foreground we will also use a X4 soft edge graduated ND filter to balance the foreground and sky.

Here is an example of a scene with little difference between the sky and the foreground. The waves were HUGE this day so I used a X4 14 stop magnetic filter so smooth them down (490 seconds) and give the feel I desired. The fog in the sky took care of itself and I walked away with a balanced ethereal image that I just loved creating! Another example of this is shown in the image below. This again was a super foggy day so the need for detail in the fog was unnecessary so the oly ND needed was again the X4 15 stop magnetic filter!

Ok, let’s take a look at a problem image where the sky has detail that you can see but when you only use a solid nd the sky is totally blown out! What you simply need is a X4 Soft Grad filter to balance the sky and water to give you a bit of detail in the sky!

These last two images show a extreme case of no balance between the water and the sky and more nd was needed on the sky to correct the imbalance.

Ok, one last thing… I had a live group hangout last night with some of my online students and we discussed everything in this post but with more info and thoughts on choosing the correct ND filters for a number of scenes. Here is the link:

https://youtu.be/_qFkUJZzXmw

I know that this has been a long post but it was necessary to show the technical side of creating pleasing long exposures. Next time I will discuss how to meter for long exposures.

As always please let me know what you think!

Using M mount glass on the Sony A7rii camera

The AMAZING just got better….

Stormy Seas with the Voigtlander 12mm Ultra Wide Heliar M Mount Lens and the Techart Auto Focus Leica to Sony adapter

Look closely at the image above. It was taken with a Voigtlander M mount 12mm Ultra Wide Heliar lens and the Techart M to FE AUTOFOCUS adapter on a Sony A7rii camera. The cleat on the bottom right is about 6 inches from the front of the lens! The color rendering is amazing and there is very little distortion that is normally found with an ultra wide lens! I can hear you asking how I accomplished this!

I recently picked up the Techart M to FE Sony mount adapter for my Leica and Voigtlander lenses. It has been my desire to use them on the Sony A7rii, A6300 and A6500 cameras.

The Techart auto focus adapter is amazing. I actually moves the lens in and out to get a sharp focus. It has several rules that you must follow to use it and as long as you do it will provide great service. It is quite fast!

Use a center focus point on the camera
Set your camera aperture to f/2 and leave. It there
Set the real aperture directly on the lens.
Don’t try to focus with the lens set to f/22, keep it around f/8 or f/11
The Exif data will shot f/2 but the exposure meter will correctly meter the subject.
Don’t try to use a heavy lens on the adapter unless you support it.

12mm Voigtlander M lens with the Techart autofocus M to FE adapter

Here is a link to a short video demonstration of the Techart M to FE adapter on my Sony A7rii:

B&W work with this lens as well as my other Voigtlander and Leica M mount lenses are just as sharp weather in color or monochrome!

Stormy Seas with the Voigtlander 12mm Ultra Wide Heliar M Mount Lens and the Techart Auto Focus Leica to Sony adapter

I also have and use a Metabones M to FE adapter which gives the same results but with manual focus only. Sometimes manual focus is necessary depending upon your subject but reguardless of focus type both adapters and all of my M lenses work wonderfully on the A7rii camera system!

Stormy Seas with the Voigtlander 12mm Ultra Wide Heliar M Mount Lens and the Techart Auto Focus Leica to Sony adapter

If you have a selection of M lenses then the cost of a M to FE adapter is well worth the money. But I am VERY impressed with the new autofocus adapter!

Please let me know what you think!

Going Home to Mama…. Returning to Film!

The joys of returning to our photographic roots…

Murrells Inlet Fleet, Polaroid Type 55 4×5 film, Wet Mount Scan

Have any of you considered film photography?

There is something about working with film that is very calming which can center one’s soul allowing you to really connect with your art. For me it was like going home to Mama. The feeling of working with your hands as part of creating your art will make it more involved and enable you to to really influence the hidden nuances in your work. It will add a bit more complexity to your workflow but trust me it is worth the effort. The single largest change is forcing you to slow down in your creative process, it forces you to really consider every part of your workflow. It really is not any more difficult than digital photography, but it is a bit more involved.

Take a really close look at the details in this image, click on it and look at it in the full screen mode. Look at the GEARING on the edge of the wheel. The detail there will take your breath away!

Film Cameras

Olympus XA 135mm

I have way too many film cameras to list them all, some really small like the Olympus XA which is the worlds smallest 35mm rangefinder and a joy to use.

I also have an Olympus RC 35 camera that is another fixed lens rangefinder. It is simple and fun to use and can be found for very little money. I have mine rebuild and given a bright blue suite that suites it quite well!

My Custom Olympus 35 RC

My Leica M7 Film Body

My last 35mm camera system is a Leica M7 system. It has interchangeable lenses and is one of the best built camera systems that I have. Couple it with the world class Leica lenses and you have an unbeatable 35mm system.

Confusion, Petri 7S 35mm, Eastman XX flim

Fuji GF670

Moving up to Medium Format 120 film systems I have three. I have the Voigtlander Bessa IIIw system that is 6×7 format and the Fuji GF670 camera (also sold under the name of Bessa III) with a longer 85mm lens (left & right). The 670 is my medium format travel camera of choice. Not only is it a functional camera with a built in meter but it is attractive and it always will draw a crowd when I get it out to use! Another nice point to the GF670 is that it folds down on itself to a thin easy to store camera in your bag!

Mamaya RZ Pro II system

And lastly the Mamaya RZ Pro II SLR ( Right) with interchangeable lenses and a world class metering system. This camera is large and heavy but easy to use and a very powerful camera system! I have a f/4 65mm and f/4 180mm lens for it. I also have both the waist level finder and a metering prism with spot and matrix! Like I said, heavy and big, but I use it for ultra long exposures on the coast with the Fuji Acros 100 film which has almost NO RECIPROCITY failure up to 140 seconds then only 1/2 stop after that! The film base is a little on the thin side but still my film of choice for long exposures.

Polaroid 900with 150mm Fujinon lens converted to 4×5

Moving up to 4×5 Large Format cameras, I have three. first I have a Shen Hao cherry field camera. Functional as it is beautiful. I rarely take it out, rather I am using a Polaroid 900 converted to 4×5 with a Fujinon 150mm lens and a Polaroid 110B camera converted to 4×5 with a Schneider Super Angulon 90mm lens. It is a beauty and very wide!

Yes, as you may have noticed, some of these cameras are quite large. This is due to the negative size. Let me give you some idea as to why digital cameras can never come close to the resolution of film.

Focus Test - Epson Wet Adapter Across 100 Perceptol 1:2 Springmaid Pi

Montreat Cascades, 4×5 Tmax 100 developed in Perceptol and wet mount scanned.

Lets start with medium format:

Medium Format 6×7 format makes an image 2 1/4 inches tall and much wider. Scanned at native resolution of 6400 dpi on an Epson 850 Pro scanner gives me a file resolution of 16452 x 19668 dpi or a print size at 300 dpi of 4.5 feet by 5.3 feet! This is huge.
Large Format of 4″ x 5 ” scanned at 6400 dpi (native) gives a file size of 29107 x 36070 dpi or a print size of 8 feet x 10 feet! There is not a digital camera system in the world that can come more than a small fraction of this!

Film

Film has turned wildly popular again in the past several years and many of the big film manufacturers have started increasing their film production lines again. This is especially true in the medium format lines (120) and 4×5 large format films! Film can be found in single rolls or in bulk almost everywhere again. The big box companies like B&H, Adorama and many others carry almost every type and format that you could ever want!

Processing in B&W has never been easier at home with eco friendly chemistry with no darkroom needed. Only an initial outlay of around $150 will get you started. Cameras can be found anywhere for next to nothing! You will need:

Dark Bag, a cloth bag that it light proof with arm sleeves that enable you to put your film, developing tank, reel an lid inside with your arms to move the film into a light tight developing tank!
Developing Tank, I recommend a stainless steel version.
Film Reels, I like the Hewes stainless steel ones.
Developer, comes either in a powder or a Liquid. I like Perceptol and/or Rodinal R09.
Fixer, to remove un-used silver
Liquid wetting agent to prevent drops to dry on your negative.
Clips to hang you film up to dry!

You can scan your film into your computer with a good Epson scanner like the 700, 750, 800 or 850. You can also buy an adapter for your camera allowing you to scan by photograph!

While I work in both color and B&W, digital and film I find time after time I pick up a film system and load it up with a good B&W film. The process of developing your film can really help you connect to your work as well.

I like several films, here they are in order of favor:

Kodak Tmax 100 in 35, 120 and 4×5, very small grain, good dynamic range easy to process
Fuji Acros 100 in 35, 120 and 4×5, very small grain, good dynamic range NO RECIPROCITY FAILURE, easy to process
Rollei IR400 in 35, 120 and 4×5, Infrared or normal B&W, good dynamic range, easy to process
Rollei Retro 80S in 35 and 120, amazing clarity and sharpness, good dynamic range easy to process
Eastman XX in 35, motion picture film used in B&W movies of the 50’s, smooth gradient transitions.

As an example here is the top image from last week of the fishing fleet taken on 20 year out of date Polaroid Type 55 monochrome instant film. The camera is also a Polaroid 900 that my daughter sent me years ago from a garage sale that I had converted to 4×5 with a Fujinon 150mm lens. A MOST beautiful camera in a bright new blue suite that is just fun to use. It is both rangefinder and ground glass focusing that forces you to slow down and really consider each and every image you capture!

The Type 55 film, even outdated, works flawlessly and generates amazing images where the edge markings add to the artistic impact of your subject

So what do you think? Are you tempted to try this out? It is easy. For starters, you can look at the continuing education departments at a local college or hight school. Most offer B&W film photography with darkroom work. This will teach you enough to allow you to determine if you would like to further investigate this wonderful medium!

You can also contact me and request info on one of my film workshops held in Pawleys Island SC. I would love to have you and share this amazing link to our past!

Overcoming the Back Focus issues of the Leica 135mm M mount lens…

Yes, HOW could such a high quality Leica Lens be so problematic….

Leica 135mm

In todays world of modern digital camera systems, the Leica M 240 really stands out above the others. One of the reason for this is the duality of an electronic viewfinder with a robust peaking focus system coupled with a real range finder focus as well! This makes this camera IDEAL for mounting any lens that can be manually focused with reasonable expectations of good focus!

But what happens if you have some of the older Leica systems like the M9, Monochrom, M8 or a film body like the M7? Should we not be able to expect the same focus quality of the M 240 using the built in rangefinder?

Well for ALL of my Leica and Voigtlander glass this has been a truism until I met the famously hard to focus 135mm lens. Now understand that this lens has been through 5 (FIVE!!) versions and each and every one has had the same bad press on their inability to sharply focus! If you ask Leica about them you are told to set your aperture to f/11, focus and shoot hoping that the DOF will overcome the shortcomings of the focus cam system inside of the lens!

Now, I badly desired a longer reach lens with a M mount but was convinced that I could not overcome the focus issues with these lenses. So one of my students from the Arcanum (a online photograph school) had one of the 135s and sent it to me to experiment with. It was one of the older models, looked kind of funky but had a tripod mount on the lens! Reviews of ALL the 135s said that this model was the best one for the money!

So with the lens on camera (M 240) I set out to test the rangefinder focus vs. Electronic focus with peaking…

Suffice it to say that the lens BACK FOCUSES so badly that unless you are shooting at f/11 or f/16 you have very little chance of a sharp image! I focused the lens using the range finder then again with the electronic peaking system and discovered the following failure:

7 meter subject. The lens needed to be adjusted to 6 meters to be in focus!
50 meter subject. The lens needed to adjusted to 20 meters to be in focus!
Infinity subject. The lens needed to be adjusted between Infiniti and 50 meters!

The adjustments were the difference between the rangefinder focus and the peaking focus!

Well….

If you were to turn over and look into the mounting flange on it you will notice that there is a focus cam that moves up and down as you focus the lens. This is NOT adjustable! But… I had an idea!

Enter High Tac Copper Tape…

High tack copper tape

Tape Application Leica 135mm

What if…

What if I were to tape one or two layers of this really sticky copper tape onto the end of the focus cam? Could I at least get the infiniti focus point dialed in?

YES! It can be done!

So, I ordered a very thin roll (1/2 inch) from Amazon, cleaned the cam and cut 1 thin sliver of the tape and applied it to the end of the cam and redid my focus tests!

After cleaning the cam with Alcohol I applied the tape, smoothing it down with a wooden dowel and allow it to sit for an hour giving the adhesive a chance to cure.

Mounting the lens again onto my M 240 I re-ran my range finder and electronic peaking focus tests on the same subjects and distances! I carefully (on a piece of tape attached to the lens marked the two focus marks for each test on the lens so that I could visualize both the size of the focus error as well as where it was on the overall focus scale.

Here are my results with only ONE layer of copper tape. I knew that my target was to get my infinity focus dead on and that the closer distance focus points would still be off but hopefully by smaller amounts.

Test data is marked on the lens showing both RF focus/Electronic Peaking focus points. The peaking points are dead on and hopefully we could bring the two closer together!

If you look at these points you will see the non cam taped focus dat on the bottom and the corrected cam data on the top. The V stands for Electronic Peaking and the M for Range Finder focus.

7 Meter Focus Tests…

7 Meter Focus Test Leica 135mm

So for the non corrected cam we see a subject at 7 meters as focused with the rangefinder, but with the Peaking focus it is moved down to 6 meters to be sharp! This is a 1 meter difference and unless you are shooting with a small aperture you will get a very soft focus! When we do the test after the cam change the difference between the range finder and peaking is actually a bit wider. This was expected…

Now, The 50 meter tests…

100 foot focus test on Leica 135mm

As you can see on the uncorrected cam side focusing at 50 meters on the rangefinder we needed to adjust down to 20 meters… That is WAY OUT OF RANGE! Yet at f/11 we can get it into focus!

With the corrected cam the difference between the range finder focus and the peaking focus gets closer together at about 30 meters which is a 10 meter reduction of focus error! Better and better!

Infinity Focus Test

Infiniti Focus tests on the Leica 135mm

Ahh, the pre cam measurement using the rangefinder sets the lens to the infinity as expected but the peaking focus sets it down about 1/3 of the way towards 50 meters. Way off to be sure but small than before.

BUT…

The corrected cam BOTH THE RANGEFINDER AND THE PEAKING focus match at infinity!! We are now dead on on the far end of the lens!

What this means is that knowing the differences between the rangefinder and peaking that we can adjust the 135mm lend down about 1/3 of the way between the major distance measurements to get much closer to being dead on. As long as we shoot at a reasonable aperture (f/8) we can be reasonably assured of a sharp focus!

I have found that these measurements are the same with the current Leica 135mm as well!

So there you have it. The online posts of issues with these lenses have been endless over the years. They are known as very difficult lenses to get a sharp focus with and now we know why and more importantly how to overcome it!

I hope that you enjoyed this discussion on what could be a very nice and powerful lens to have in your bag!

Using Fumed Alumina To Fix Paper Issues in Van Dyke Brown

An Easy & Cost Effective Way To Fix Paper Issues!

Stormy Seas, Van Dyke Brown, Lana Paper, Fumed Alumina Brush Coated, Gold Toned, 720nm Infrared

Testing Fumed Alumina…

Van Dyke Brown emulsion is basically on the acidic side of things chemically and as a result of this I have been forced to wash most of my papers with a acid bath. This caused a increase in my process by 2 days. So I am testing Fumed Alumina which is acidic unlike Fumed Silica which is neutral. I decided to go with the Alumina test first and will do a followup post down the line with the Fumed Silica.

Bent Tree, Van Dyke Brown, Lana Paper, Fumed Alumina Brush Coated, Gold Toned, IR400 120 Film

Initial results were quite pleasing with both Revere Platinum and Lana Aquarelle papers. I got a MAJOR increase in Dmax with both the Lana and Revere papers, but upon completion of my final wash the Revere was VERY EASY to damage with finger smudges until it dried. The Revere had a tendency for the Alumina to easily rub off the Alumina while wet whereas the Lana was strongly attached.

Anderson Mill, Van Dyke Brown, Lana Paper, Fumed Alumina Brush Coated, Gold Toned, Leica M Monochrom

The Alumina did fix ALL of the spotting issues that I had when using the Revere Platinum paper but the fact that it will rub off when wet causes some concern but it is easily overcome with careful handling.

Magnolia, Van Dyke Brown, Lana Paper, Fumed Alumina Brush Coated, Gold Toned

The Process:

Dry roll on the Fumed Alumina in 2 directions and rap the paper edge on the table to remove the excess. Make sure that you use a good mask to filter out this dust as it might irritate your lungs. DO NOT OVER COAT or you will get streaks when you coat the emulsion. The rolling step only takes about 30 seconds! You will need to put about 1 TSP of the Alumina into a small paint tray then pre load a small (3″) HARD foam roller with it.
Coat as normal after you roll on the Alumina. You will need about 12 extra drops of VDB emulsion due to it absorbing more. My basic quantity of VDB emulsion for a 8×12 sheet of paper coated with Alumina is 48 Drops of emulsion and 2 drops of Tween 20 at 25% (you will need to dilute the Tween from 50%) solution. For this post I brushed on the emulsion. In the past I would normally use a glass rod for coating but the Alumina creates a very rough surface and I was afraid of damaging the paper.
Dry and Expose. Here you will find that the addition of the Alumina will DECREASE your exposure about 1.5 stops!
1st water bath with distilled water and a pinch of citric acid, 2 min. This bath will remove any extra ferric ammonium citrate which will cause a yellow paper stain. This bath will darken the print. Do not worry as the FIX will balance contrasts and bring out the highlights!
Fresh water bath to remove citric acid. 2 min. If you are Gold Toning, this step is VERY important as any Citric Acid will destroy the toner bath!
Gold toning bath 2 to 5 min to taste. The toning process requires CONSTANT AGITATION! After 2 or 3 prints toned add 5ml/print of Gold Chloride to bring the bath back up to strength. This toning bath will further darken the print. Do not worry as the FIX will balance contrasts and bring out the highlights!
Fix for 2 min with Sodium Thiosulfate for 2 min. 30g/L. I do not believe that any further time will help the process.
Final moving fresh water bath for 30 min.
Air dry, I spread out old towels on a table top and place the print on it for about 10 min to absorb most of the water thru the back of the print. I will then hang the prints to dry by a corner.
Use a heat press to flatten your prints at 170deg for 20 seconds. The heat press step is to make the paper flat again.
Hand rub in SOFT custom wax coating for protection then heat to force the wax to be absorbed into the paper fiber with a hair drier (more about this in a future post).

Dinghy, Van Dyke Brown, Lana Paper, Fumed Alumina Brush Coated, Gold Toned, Leica M Monochrom

All in all this was a VERY easy fix to the acid washing step and only added about 30 seconds to roll on the Alumina. The Fumed Alumina can be purchased at Bostick & Sullivan for $15/500g which will do about 100 sheets of 8×12 paper.

The increase in Dmax with the Fumed Alumina is amazing and the resulting images are stunning.

Please let me know what you think of this post and with suggestions for future posts!

After experimenting quite a bit with washing my un coated Lana paper with a 2.5% wash of Citric acid and distilled water and discovering that ALL of my paper issues fell away that the Dmax of my paper/print would so radically improve! Though I do have to admit that pre washing the paper adds 2 entire days to my workflow and is a LOT of work. I recently ordered some Fumed Alumina powder from Bostick & Sullivan as an alternative to acid washing. B&S says of Fumed Lumina:

A small quantity of fumed Alumina is rolled on to a piece of paper with a dry high density foam paint roller. It spreads evenly on to the paper leaving a velvety surface to the touch. The paper can then be coated with a platinum/palladium solution, dried, exposed and developed in the standard method. It is suspected that the Alumina can be used for other hand coated photographic processes like cyanotype, van dyke, Kallitype, and similar processes. It has already been tested with great success with albumen prints. The coating acts as a sizing enhancer and appears to protect the emulsion from alkali buffers. Contrast increases but appears largely to be due to enhancement of the blacks.

So, this then is the great experiment of March! I will report back on the measured effect as it applies to my process in the next post!

Now, onto the reason for this posting, Gold Toning of Van Dyke Brown prints! Now that I am getting consistent prints from my acid washed Lana Aquarelle 140lb HP and Stonehenge papers I wanted to explore increasing the Dmax further by Gold toning. Rather than mixing my own gold toning solution (basically I am very lazy) I decided to purchase Bostick & Sullivans Gold Toning liquid solution. This is simply 2 bottles of a chemicals, solution A is 2% Ammonium Thiocyanate and solution B is .2% Gold Chloride. You mix 50ml each of A and B with enough distilled water to make 500ml of working gold toner. Easy peasy, no powders to measure and mix. B&S says that you can replenish the solution by adding 5ml of the Gold Chloride for each 8×10 print you tone. I do this in the toning bath but when finished I am thinking that I need to throw it away and treat it more like a 1 shot toner. Since the cost of the Gold Toning kit is so reasonable from B&S ($45) and will make such a large amount of working toning bath 10 bottles of 500ml working bath I am inclined to do so.

Magnolia Blossom, Gold Toned Van Dyke Brown Prints on Lana Aquarelle 140lb HP paper

The reason for this is simple. It has to do with the processing sequence:

Expose your coated paper.
1st water bath with 2000ml of distilled water and 1 tsp of Citric Acid for 2 min to remove excess sensitizer (yellow Stain) from the paper and to help prevent emulsion wash off.
Gold toning bath, watching for toning in the mid tones and highlights to indicate finish.
2nd water bath with 2000ml of distilled water and 1tsp of Citric Acid.
Fix.
Rinse in tap water for 30 min.

The issue for me with replenishment of the gold toner solution is that even the TINIEST amount of citric acid will destroy the toning solution. So this means that between step 1 and 2 I have to insert:

1b. Plain tap water bath for 1 min to remove Citric Acid.

Since the Citric Acid will destroy the gold toner and that there is very little chance for me to remove most of it prior to toning then there is the very likely chance that it will be ruined even with a plain water bath prior to toning!

The acid problem with the gold toner is the only real issue to its use. I really do not want to have to put the print into my print washer for 5 min to clear all of the acid so a 1 shot toning bath for about 3 images seem a good trade off to me. Time will tell!

I hope that you have been paying attention to the images spaced through out the post. All of them have gone thru the gold going process and with the exception to the last one I did not add any more Good Chloride to the bath. Because of this you can notice that with the exception of the 1st and last print each print after the 1st look more brown as we progress down the line! With the last one I added 25ml of the gold to bring the bath back up to strength and you can see the difference. You can tell that it is run down by how long it takes for the toning process to complete to the point where you like the results. I have been told by friends online that I could have taken the toning process a bit further. The thing about gold toning is that the gold replaces all of the silver in the print which shifts the print colors from dark brown to a very platinum looking black. You can even get a bluish tint in the dark tones of your print!

I think that the toning process is VERY worth while and highly recommend that you give it a try.

The next post should be on using the Fumed Alumina as an agent to overcome a non-acidic paper coating as well as increasing the prints Dmax!

Van Dyke Brown Printing, 1842

A new (read OLD) way of printing!

8×12″ Van Dyke Brown Print

Alternative Printing from History!

Van Dyke Brown is an early photographic printing process. The process was so named due to the similarity of the print color to that of a brown oil paint named for Flemish painter Anthony van Dyck.

The Vandyke brown print is based on the first iron-silver process, the argentotype, invented in 1842 by the English astronomer, Sir John Herschel. Both processes utilize the action of light on ferric salts and their chemistry is very similar. The Vandyke process gets its name from its similarity in color to the deep brown pigment used by the Flemish painter Van Dyck. Vandyke brown prints are very simple and economical to make, with the sensitizer consisting of three readily available chemicals. Clearing is carried out in water and fixing is done in a weak solution of hypo.

Van Dyke Brown Step Wedge Calibration Chart for 3 Min Exposure

As you can see, this is a very early way of printing developed a long time before our current Silver Salt paper process. The images are a deep brown instead of the normal black and white that we are used to seeing. They are somewhat easy to create provided that you have done your homework and created the proper calibration images to create a calibration Gradient Map or Curve to apply to your negatives which adjust them for loss of mid tones in the printing process.

This is strictly a CONTACT PRINTING technique that requires a true negative that is placed on top of paper that YOU as the artist coat yourself with the Van Dyke Brown emulsion that you mix from simple chemistry! The coating process is done with a special brush that requires a very light touch or a glass coating rod that you use to push a line of liquid emulsion across the paper.

B&W Negative for Van Dyke Brown Print exposure calculated for 3 Min with the calibration applied.

The liquid emulsion is measured by the number of drops from a glass eye dropper into a small glass then with a drop of two of a wetting agent like Tween 20 to help the coating process. The paper/emulsion is allowed to dry then the negative which was created using my Epson 7900 printing on transparency material is placed on top of the coated paper. This sandwich is then placed in a printing box filled with 12 Fluorescent Black Light tubes which then expose the paper with UV light. The exposure for the current paper I am using (Revere Platinum) has been calibrated to 3 or 4 min based upon the test chart above.

Van Dyke Brown Print, Over Exposed by 2 stops.

Van Dyke Brown Print, Over Exposed by 1.5 stops.

This process is a POP process in which the image after being exposed can be seen on the paper once removed from the UV box. It is orange and yellow in color. It is placed in 2 consecutive distilled water baths that remove the yellow and darken the orange. Then it is placed in the fixer solution (Sodium thiosulfate) for 2 min. When the image is placed in the fix, it IMMEDIATELY changes from orange to a very dark brown and white picture. Finally the print is placed in a live water wash for 30 min then dried!

This is a simple process that creates beautiful images that will leave you breathless as you view them! I am going to further develop and learn the process over the next month or two before I start on mastering the Platinum/Palladium printing process as well!

Look forward to many more posts on the processes as I master them!

Going Home to Momma with the Leica M7…. Film Photography Returns!

Ahhh… It Feels So Good!

Spring in the South… Rollei IR400 Film – Leica M7 50mm Lux – Rodinal 1-50

Oh my, I do NOT know where it came from but I got the BUG again for more film photography! I have a cabinet here in the Gallery just full of old film cameras plus a Leica M7 film body that works with ALL OF MY M MOUNT LENSES! (see the last post HERE for more info on the lenses). I decided to purchase a new stock of several films:

Kodak Tri-X 400, Ohh
Eastman Double X 200, Ahh
Rollei IR400 400, WOW!
Kodak Tmax, Ho hum…
Ilford HP5+ 400

Rodinal One Shot

I picked up some stainless 2 roll developing tanks with a bunch of Hewes (don’t skimp on your reels, buy the best!) Stainless Steel 35mm Reels. For developing I like Rodinal One Shot due to its ease of use and a life span of around 40 years. I simply mix it one tank at a time usually at a 1:50 ratio with water using a small syringe. It allows a very wide latitude of contrast and iso control. I have used several other developers but I keep coming back to Rodinal!

Now, I am playing with several cameras. As I said my main and BEST camera is my Leica M7. But here is a current list of those cameras I am using:

Leica M7 with Leica & Voigtlander Lenses
Petri 7s, 1962
Olympus XA
Olympus 35 RC
Shen Hao 4×5 Field Camera (about 12 years old)

1962 Custom Petri 7s Film Body

The Petri 7S has been in my hands since 1962 and still shoots great ( I did send it off to have the light seals replaced and a new leather covering ). The Petri has no batteries but rather a solar cell around the lens that drives a needle exposure meter that you simply place into its center notch for a good image!

All of the cameras in my list above have proven reliable but with the Petri you get a link to the past, specifically MY past as this was my 2nd camera I owed when I was young!

The Olympus 35 RC is an amazing small rangefinder with very nice controls. It is smaller then the Petri 7s and actually has better control functionality. It does require a battery to run its metering system though which is a step down from the Petri 7S in my opinion. The nice thing other than the size is the fact that EVERYTHING is displayed inside of the viewfinder. Unlike a refurbished Petri 7S which can be found for around $100 used on Ebay, the Olympus 35 RC camera refurbished is demanding around $250! This is a big difference in price and tells you a lot about its quality and demand! I was lucky to find one from a collectors inventory that he sent off to be totally refurbished and re-skinned for much less than $200.00! For you film shooters out there on a budget this is the camera that I recommend if you find yourself desiring a rangefinder.

My Custom Olympus 35 RC

The Olympus XA was a 35mm rangefinder camera built by Olympus of Japan. It was one of the smallest rangefinder cameras ever made, together with the Contax T.

Olympus-XA

It was designed by Yoshihisa Maitani who had joined Olympus Optical Co Ltd in 1956. He was the chief camera designer and managing director of Olympus Optical Co Ltd., having developed a number of legendary cameras during his career. These included the Pen series, the OM series, the XA series, the IS series and the [mju:] series of cameras.

The original model, the XA, was sold from 1979 to 1985. The original XA features true rangefinder focusing, a fast 35mm f/2.8 lens, and aperture prioritymetering. The lens was protected by a sliding dust cover.

This is the smallest 35mm rangefinder ever made. It will fit in the palm of my hand and will make a great system to have with me everywhere I go!

The Leica M7 uses batteries and sports a center weighted spot meter measured either off the film or off the shutter. I find that it meters very reliable. It is the top of the heap when it comes to 35mm film cameras. There are a lot of high end rangefinder cameras on the market but the Leica is the top. I really excels in the area of long exposures with either a count down timer in the viewfinder for images metered and controlled in the aperture priority mode or a count up timer for exposures done in the bulb mode. In bulb, it will count up to 16 min then stops counting for battery conservation, but will continue exposing until you release the remote shutter release. It will use NO battery power after the 16 min count up timer turns off until you release the shutter then it requires a pulse of electricity to close the shutter. NO other rangefinder can say this unless you use a pure mechanical camera like a Leica M2 which has no metering system at all.

The Leica M7 is surprisingly heavy but easy to handle. I keep reading about other high end rangefinder bodies out there but when you do the comparison of features I always come back to the M7.

My Leica M7 Film Body

All of my cameras are fun to use and reliable. With the Leica M7 you get the world class glass but with the Petri 7S you get a link to the past, specifically MY past as this was my 2nd camera I owed when I was young! The Olympus 35 RC is an advanced rangefinder from the 1970 era and is slick and fun to shoot. You will see examples from these cameras towards the end of this post!

______________________________________________________

I usually develop my negatives on Sundays. I have a film drying cabinet that I use to dry the film without dust spots overnight. I then will scan the negatives on Monday or Tuesday using a Nikon 4000 ED film scanner at 4000 dpi into the DNG format for editing and cleaning later in the week. I usually shoot 2 or 3 rolls a week.

Rollei IR400 Film

My favorite film is Rollei IR400. This is available at the big camera stores like Digitaltruth, Freestyle and B&H. What makes this film so special is the fact that is very much like Kodak Tri-X 400 as shot. It has a VERY THIN film base which really makes scanning easy. BUT the most amazing thing about this film is that it is sensitive to INFRARED! If you place a Hoya R72 IR filter on the camera lens the film will record 720nm IR images! There is an ISO hit due to the filter being so dark down to 12 ISO but it is worth it being able to shoot in both normal B&W and IR B&W!

Next I like the Kodak Tri-X 400 film. It gives great contrasts and has a very wide latitude in development. It is well known and tested and for ultra long exposures.

Eastman Double X 5222

Then comes Eastman Double X Cinema film. This is a GREAT B&W film that gives a very smooth gradation and lovely warm tonality with slightly increased contrasts. This is motion picture film so unless you are going to buy a 400 foot reel you will need to purchase it from the store at Film Photography Project. They will sell it in either 24 exposure rolls or a 100 foot bulk loader roll. It develops nicely in Rodinal at 1:60 for ISO 200 but there are ratios for 100 up to 800 ISO! This film is very much worth experimenting with.

I need to say a few words about the folks at Film Photography Project. They offer an amazing wide selection of films and old cameras! This includes Polaroid cameras and film also! Their Podcast is amazing and I find that it is so good that I now have it running all day while I am working at my gallery in Pawleys Island. Good Stuff, check them out here: Film Photography Project.

Whatever film you decide to use you will be pleased with the results. Processing is easy to do with a VERY small investment. You will need:

Film Camera
Film
Chemestry: Developer, Stop (you can use water), Fixer and water bath with a Wetting Agent. $40 to get started

Film drying hanger clips $3 for a bag of 2
Film tank, either stainless steel or a Peterson. Peterson tank and reel is about $40
Film tank reels (if stainless do not skimp on these). Hewes Steel are about $25 each
Dark changing bag to move the film from the canister to the developing tank. $40
You will also need some way to scan your film into a digital image or pay someone to do it for you.

That is it. It normally takes me about an hour to develop 2 rolls. I will let them dry for several hours then cut them into strips of 6 and put them into plastic storage sheets.

For scanning, as I said above, I use a Nikon 4000ED film scanner. As you can guess from the name it will scan at 4000 dpi and has a lot of adapters for different types of film scan feeders. It has slide auto feeders, single slide feeders, a 6 position film rail for troublesome film and an automatic roll feeder to scan entire rolls automatically. If you couple this with VIEWSCAN software you have an amazing scanning system that rivals those that pro labs use!

Nikon 4000 ED system

Ok, lets take a look at the results of 3 types of film in 2 cameras!

I hope that you enjoyed this post and its associated images. I have been using film since I was 9 years old. At 13 I had my first darkroom at home. I worked in film in my own darkroom until I was 18 when that period of my life can to an end. 42 years later I re-engaged film photography again and cannot help but ask “Why did I wait so long?” I have been shooting digital since my career at Eastman Kodak when you could ONLY get B&W digital camera systems! I have spent fortunes on digital and have loved every moment of it. Film will NOT take any of that away, I still have digital and continue to use it. But I have to be honest and admit that working in film again fills me with a sense of peace that I have not experiences in a very long time….

The Peace Of The Creative…

Slowing down creates peace on multiple levels.

For you as the photographer and for those who view your work, this has never been more true!

I am going to do a slightly different type of post this time.

We will discuss the art of Long Exposures a bit but we will focus more on the technical aspects of using ND filters to correct for different types of lighting as well as talk about good ND filter systems verses not so good, and why it is always best to invest your money in good filters!

Definition: Long Exposure – To create an image in camera with the shutter open for longer than a few seconds in order to smooth out movement over time. This can be softening the flow of water over a waterfall, flattening of waves in lakes and oceans or tearing clouds moving across the sky.

First, there are a few points to consider when thinking about using ND filters:

Ok, one last thing… I had a live group hangout last night with some of my online students and we discussed everything in this post but with more info and thoughts on choosing the correct ND filters for a number of scenes. Here is the link:

I know that this has been a long post but it was necessary to show the technical side of creating pleasing long exposures. Next time I will discuss how to meter for long exposures.
