Using Fumed Alumina To Fix Paper Issues in Van Dyke Brown


An Easy & Cost Effective Way To Fix Paper Issues!

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.

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.

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.

The Process:

  1. 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.
  2. 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.
  3. Dry and Expose. Here you will find that the addition of the Alumina will DECREASE your exposure about 1.5 stops!
  4. 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!
  5. 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!  
  6.  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!
  7. Fix for 2 min with Sodium Thiosulfate for 2 min. 30g/L. I do not believe that any further time will help the process.
  8. Final moving fresh water bath for 30 min.
  9. 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.  
  10. Use a  heat press to flatten your prints at 170deg for 20 seconds. The heat press step is to make the paper flat again.
  11. 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).

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.

Continued Work In Van Dyke Brown Alternative Print Process!


Perfection in Brown…

After another 2 weeks working on the negative density, I have finally gotten to the point of good negatives, not great yet but I will get there.  I have to master the use of UV blocking color in the negative for them to be perfect and that is a project for the future. To date though I have reached perfection using normal B&W negatives.  

My CORRECTED Digital Negative for the Van Dyke Process

My CORRECTED Digital Negative for the Van Dyke Process

Here is the corrected negative that I used in the image of the Oak trees above.  It is much dense and has been corrected for the mid tones as printed in the Van Dyke Brown Process!  It has much greater contrast and required only a 3 min exposure in my UV unit. 

One thing that you have to remember when making your UV exposures is to place the ink side of your negative down on the paper surface.  If you reverse this the picture will be backwards, but more importantly, the UV light will burn the ink surface and ruin both the negative and the print.

B&W Negative for Van Dyke Brown Print exposure calculated for 3 Min.

B&W Negative for Van Dyke Brown Print exposure calculated for 3 Min.

Compare it to the negative on the right.  This negative was used in the previous post here where the image printed much darker and with less mid tone data.  Take a close look at the difference between the two negatives, the first has much brighter areas for increased black contrast and more detail in the trees. The difference is amazing and was easily achieved by the process discussed below…

Here is a small copy of the print generated by the 2nd negative from the previous post.  Notice how much darker it is and that there is no detail in the mid tones of the image!  It only took me a short while to create the Gradient Map from the process that I learned in Peter Mrhar’s book below.

Easy Digital Negatives is another remarkable book by Peter Mrhar that I use in the creation of my negatives.  It enables you to easily create Gradient Maps to adjust the mid tone values of your negative tailored to the alternative process that you are printing with!  I highly recommend this text over all of the others!

There are several good books on Digital Negatives out there but As I said the is the easiest that I have read and used plus the results of using a Gradient Map over a Custom Curve.  I suggest that you purchase several texts and try them in your workflow to see what works best for you!

I hope that you enjoyed this short post on the Van Dyke Brown Process.  You can look for more about it in the future!

Going to the Dark Side: 830nm Infrared and the Fuji X100s


830nm Infrared Conversion on the Fuji X100s

 

Oak Reflections, 830nm

Image 1:  Oak Reflections, 830nm

 

Infrared photography with digital camera systems have been around for several years now and a lot of photographers have embraced this different spectrum of photography.  Infrared is wildly popular in photography and fine art galleries now and my workshops are full of lots of talented photographers who desire to learn or expand their infrared skills.

Pawleys Marsh, 830nm X100s

Pawleys Marsh, 830nm X100s

The typical starting point for most infrared shooters is 720nm (standard) or 590nm (Goldie) IR conversions. We have all seen the amazing color images that these two conversions can generate. As previously discussed, we always process not only in Faux Color, but for B&W also. The B&W images are usually more accepted among the arts community though.

Pawleys Marsh, 720nm

Image 3:  Pawleys Marsh, 720nm

 

But did you know that with each increase in the IR Nano Meter band (the frequency goes down as the number goes up) that the contrast levels go up in B&W as well? This increase in the NM band starts to generate the most stunning, contrasty, ethereal images that have to be seen to be believed! The higher you go in the NM range also increases the white “glow” around the leaves and grass and the blue sky takes on a deep black. This effect is named the “Wood Effect” after doctor Robert Wood who discovered it 1910. What happens is that the leaves get a bloom or glow of white around them that generate that wonderful ethereal feel in the image. Take a look at image 1 which was taken at 830nm. Do you see the dark black where the blue sky is? Look at the leaves on the trees and how they take on the pure bright whites! Now compare that to 720nm image above in Image 2. The most striking difference is the gray sky rather than black, plus the leaves are grayer rather than white.

Shrimp Boat at 830nm

Image 3: Shrimp Boat at 830nm

 

I would like to suggest that if you shoot in IR or are interested in doing so then you should consider a deep contrast IR conversion beyond 800nm. There are a lot of benefits to be found in that spectrum. This new spectrum sees ONLY in B&W, which will force you to visualize your scene in B&W.

 

The benefits to a Deep B&W IR conversion are:

  • Extremely sharp images.
  • Wood Effect bloom on plant leaves.
  • Dark moody skies.
  • Only works in B&W
  • Post processing is easy and quick using Nik Viveza and Silver EFX for texturing and contrasts. Photoshop CC, Elements or Lightroom, they all work for Deep B&W IR!
  • White Balance is easy.

 

Mabry Mill, 830nm

Image 4:  Mabry Mill, 830nm

There are several ways to have a camera converted to deep B&W above 800nm.

  1. The easiest is to simply take ANY digital and have it converted by removing the internal UV/IR blocking filter and replacing it with a 800nm, 830nm or a 850nm internal filter. With this type of conversion you can use any digital camera type or style because only the sensor will see the infrared light and you will either see the scene via the optical path or via a live view from the sensor. Typically, this type of conversion should cost around $300 to $350 thru any of the normal conversion companies.
  2. If you are shooting a Full Spectrum or Dual Spectrum conversion then you can purchase and attach a B+W 093 830nm filter to your camera lens! This filter blocks ALL visible light so you MUST have a camera with a live view only to use this otherwise you will never be able to see thru the optical path to focus and compose. The Full Spectrum camera is one that has had the internal UV/IR blocking filter removed and replaced with clear glass and the Dual Spectrum conversion is where the internal UV/IR blocking filter is removed and replaced with a strong UV filter.
Rock Run Mill, 830nm

Image 5:  Rock Run Mill, 830nm

 

With either the full or dual conversions you can shoot every of the following light spectrums:

  • Ultra Violet                                               Full Spectrum *
  • UG1 UV & IR                                            Full Spectrum *
  • 047b In Camera Faux Color                  Full Spectrum *
  • 530nm Faux Color                                  Full & Dual Spectrum
  • 590nm Super Color                                Full & Dual Spectrum
  • 630nm Pinkie Faux Color                     Full & Dual Spectrum
  • 665nm Enhanced Color                        Full & Dual Spectrum
  • 720nm Standard                                    Full & Dual Spectrum *
  • 800nm B&W                                          Full & Dual Spectrum *
  • 830nm Deep B&W                                Full & Dual Spectrum *
  • Normal Visible Color                            Full & Dual Spectrum

* Requires Live View capable camera

 

Now, Normal Visible Color simply means that your camera can take normal color images as it did from the factory! This means that you have a multi purpose camera that can take anything.

The only issue is that if you have a Full Spectrum conversion you need to stack a B+W 486 reflective IR/UV blocking filter on your lens with a LDP CC1 absorption filter to get back to good normal color.

For the Dual Spectrum conversion you only need to put the B+W 486 reflective IR/UV filter on your lens and it is back to normal color!

Disadvantages to the Full or Dual Spectrum Camera Conversion:

  • More expensive to convert.
  • External filters for each of our lens sizes.
  • Color filters (530 – 665nm) are not expensive but the B+W 093, B+W 486 and the LDP CC1 filters are VERY expensive.
  • Your camera MUST have a live view mode to focus and compose.

 I have several cameras converted to above 800nm and several full spectrum and a new dual spectrum converted Fuji X100s. The images that I am getting from the Fuji with a B+W 093 830nm filter are the sharpest and most stunning deep IR images that I have ever produced! But that doesn’t mean that you need to go out and purchase that one. Any camera with live view will work great with the 830nm spectrum. Keep in mind though, that the more modern your camera is the higher the usable ISO will be!

I attempted IR several years ago and was totally frustrated when it came to post processing.  Despite enrolling in an online course and spending hundreds of dollars on IR books, it was a hit and miss proposition in getting any decent images. Everyone said the same  thing – “swap your red & blue channels in Photoshop”.  Sorry, that doesn’t work all of the time.
Everything changed after taking Mark’s IR workshop.  Now it’s even easier to learn IR though this wonderful DVD set.  Get your White Balance right in the beginning, watch your red channel in your histogram, then follow Mark’s IR post processing methods.  He makes it that simple.
 Mark is truly a master!

Mark, I demand my money back on the IR & Color Post Processing Video tutorial ! How dare you sell DVD of that quality for $30 when it is easily worth 3 times that amount!  Mark – this was the best training DVD I ever saw.  You covered everything perfectly.  I watched it twice yesterday and intend to watch it again today.  You covered everything perfectly. You are truly a master!  Thanks

________________________________________________________

The DVD arrived today, thank you. The cover, case, packaging all looks great: very professional.  Will delve into it while traveling next week.

________________________________________________________

I really like your suggested folder structure, of leaving the original RAW files untouched, then having a separate Develop folder, for work in progress images, and another Archival folder for final, processed images. I’ve spent the past 5 years processing my original RAW files. Goodness know what damage I’ve done. Your system is much smarter. Thank you!

________________________________________________________

I have Ingestamatic working reasonably reliably now and am coming to appreciate its utility in naming files and organizing sub-folders. It’s certainly smarter than any other uploading programs I’ve used.

________________________________________________________

I love my videos!

I would like to thank those who have taken the time to send feedback and comments!  It means a lot to me and will help improve on the next Video Tutorial that I put together!  

Please keep them coming!

Fuji X100s: Oh Yea…


You know the feeling, and usually need tissues to clean up afterwords!

A little background is in order…

Fuji X100s

Fuji X100s

Fuji X, what can you say except “Yes Please!”.  I am a LONG time X shooter.  I started out several years ago with the Fuji X100 and loved every moment of it.  I likened shooting with it to going home to Mama…  If you know what I mean then you understand.   I did decide that I really desired to have a camera with interchangeable lenses and when the Fuji X Pro 1 came out I jumped on it and all of the FX lenses that have since arrived plus several CV lenses as well.   The X Pro 1 has become may main goto camera system.  I Then purchased the X-E1 due to its electronic shutter release, thus its ability to connect to my lightning trigger and water drop computer system!  The X-E1 only lives for such things…  When I get it out to play with lightning it is like coming home to a doggy after a long day! I then decided to get another X Pro 1 and have it converted to 720nm Infrared.  This system (my 16th IR conversion) is the BEST IR camera that I have ever used and that is a big statement!

So, along comes the X100s, and I look it over and think on it for months.  I though that gee, what a neat system to add to my bag.   Finally I decided to get one but let me tell you that they are HARD TO FIND!  I found on at a little online camera store in Oregon and had them ship it to me last month.  I am very glad I made  this decision!  To say that the X100S is a world class camera is really short selling its capability!   I find that I carry it EVERYWHERE I go now.  I still use the X Pro 1 for most of my work but the X100s really gives stunning results and the new XTran 2 sensor is amazing.  I love the split image manual focus system and wish the other Fuji cameras offered it as well.

The X100s works very well in macro mode and the sharpness, colors and texture are simply breathtaking!  You could not ask more of a walk around camera than the Fuji delivers.  Even without image stabilization the camera is flawless due to its ability to shoot cleanly at high ISOs!

UPDATE: Fuji X Pro 1 and Advanced HDR Photography with NIK, Photomatix & Merge


WOW, the world sure changes fast if you close your eyes!

OK after one of my readers left a comment suggesting that the new version of Nik’s HDR EFX Pro 2 was likely supported in Lightroom I decided that I should perhaps do a little research!

Here is what I found:

Detailed compatibility specs for NIK HDR EFX PRO 2

So, as you see, as long as you are running a 64 bit OS plus very specific hardware in the graphics department it seems as if you can now run this fine HDR tool in Lightroom and Aperture!

Nice upgrade Nik!

Fuji X Pro 1 and Advanced HDR Photography with NIK, Photomatix & Merge


Or, Look Mom at  what I made!

A brief overview of the  4 major HDR tools…

The Glade Creek Mill, Fuji X Pro 1 w/ 60mm lens, 10 stop ND and Nik HDR EFX Pro 2 with 3 source files

I just got back from a major workshop that Jamie Davidison and I led to the New River Gorge in West Virginia where to took our students on a hectic 4 day workshop/excursion.  We explored waterfalls, grist mills, trains and vistas while studying Infrared and Color post processing back in the classroom each night till about midnight.  This was EXHAUSTING to say the least but never the less, a great workshop full of great photographers who gave as much as they took!  My days started every morning at 5am and ended about 1am.  I am still recovering!

The Glade Creek Mill, Fuji X Pro 1 with the VC 12mm lens

While the main focus was shooting in Infrared and its associated post processing, I needed to provide loaner IR camera systems to those who did not yet own one, so even though I own three IR systems I was forced to shoot color!  The sky each day was free of clouds and very bright, so if I wished to photograph in color I was forced most of the time to shoot HDR images in order to overcome the dynamic range of the day!  A lot of the time I was able to successfully capture an image with The X Pro 1 in a single shot like the one shown here on the right of the Glade Creek Mill.  But the norm was indeed HDR. The X Pro 1 camera has an unfair advantage over most other camera systems, it has a wider dynamic range and can capture more image data!

Notice that the mill did have some running water which forced me to use very long exposures in the range of 10 to 5 seconds in order to slow the water down.  While there was not a lot of water flow there was enough to make the images very nice.  I used the 60mm lens on the camera along with a 10 stop ND filter in order to slow it down!

OK so let’s get to it!  From this point on, we are going to be working with the same three source files.  I will take you through the post processing for the following HDR tools:

  • Nik HDR EFX Pro
  • Nik HDR EFX Pro 2 (new)
  • Merge To HDR Pro (Photoshop CS6)
  • Fotomatix Pro 4.2.3

I also will be using Nik’s Color EFX Pro 4 and Viveza 2 for post processing (fine tuning) after the HDR conversions are finished!

Overview:

OK, what is HDR?  HDR stands for High Dynamic Range.  Think of it this way… You are out taking pictures during the brightest part of the day.  You can get a good image of the foreground subject, but the sky is totally blown out, you know pure white.  The total range of the light from black to white in your image exceeds what your camera is capable of recording, but our eyes can still see and understand the complete range.  So, in the world of photography, we have developed the ability to take several photographs, say three to six, each one with a different exposure from way too dark to really blown out.  With these pictures in hand you can now run one of several software programs available that will combine the best of each of these differently exposed image into one that can display the entire range of of the image from black to white!

Now this requires a image with more data than you can store in a 8 bit JPG image, and even more than your 16 bit RAW, TIFF or PSD image!  Now we move into the world of 32 bit images that can hold and display  a far greater range of black to white data.  Now, 32 bit images are all but useless to us in the real world so the HDR software will compress it down to 16 bits by removing select bits of brightness data without really negatively affecting the view of the image and making it possible to view and print the image!   Pretty neat technology don’t you think?

What I normally do when shooting HDR is to take a test image and evaluate the histogram.  I will look to see what areas are out range, or totally black or totally white.  Usually, the blacks will be fine but the whites will be blown out.  I will then retake the same image with a negative EV dialed in and re evaluate the image again looking to see if the blown out white areas of the image are now in the proper range.  This gives me an idea of just how wide the range of the image needs to be.  If the blown out areas take two or three stops of adjustment to bring them back into range then I will then  decide upon how many HDR images are needed to be taken to get the total range covered in 1/2 stop increments.  You will need to set your camera on a tripod and have it locked down to assure that you get the same exact composition in each shot.  You can either use the auto bracket mode on your camera to generate your shots or do it manually.   Weather or not you change the ISO or shutter speed is dependent upon the scene or your artistic intent.  Some cameras will bracket at most three shots, some 5 and some even 7 or more!  You can usually choose to bracket with Aperture, Shutter Speed or ISO.  It is important to keep the Aperture constant as to not change the depth of field.

For these shots, as long as I kept the shutter speed longer than 3 seconds I would not have any issues with keeping sharply defined slow moving water to generate the HDR.  So I chose a 3 stop bracket using the Shutter Speed, leaving the Aperture and ISO steady.

Here are the 3 component images that make up the final HDR image:

  • In the first, 3495, the trees and mill look good, the water is overexposed about a stop and has lost detail and the rocks are a little under exposed.
  • The second, 3496, the rocks are perfect but the water is very over exposed. There is some detail in the black area under the top of the falls.
  • The last, 3497, the water is perfect but everything else is just to dark.
  • The water was always the key to this shot, getting it so that it was not blown out is the reason to use HDR.  These three images generated by the camera without any processing other than raw conversion and bracketed .7 ev apart with -1.3 ev being one of them, -.6 ev and lastly –2 ev.  If you decide to try this, keep in mind that the closer together the exposures are, say 1/2ev the more data you will have to generate your final image.  You can also add more data with more images. Every HDR you setup and shoot will be different and you must evaluate how many shots to take at what exposure.
  • The very dark black under hang below the top of the waterfall was another consideration when deciding the exposure values of the component images.  I needed a brighter image to bring out some detail here as well.

3495, -1.3 ev, f/8 8 seconds, I chose this value to get the correct exposure on the trees

3495 Histogram, -1.3 EV

________________________________________________

3496, -.6 ev, f/8, 13 seconds. I chose this value to get the rocks and mill exposure correct knowing that the water would be blown out

3496, -.6 ev

________________________________________________

3497, -2 ev, f/8, 5 seconds,  I chose this exposure for the correct falling water exposure

3497, -2 EV

________________________________________________

These three images are the only ones that I will use to explore the various HDR processing software.

Final considerations on component images that make up the HDR image:

  • You MUST shoot on a tripod to control camera movement (prevent ghosting) and to lock the composition.
  • Use a remote shutter release.
  • Wind will cause plant and tree movement which will cause a ghosting effect (bad).
  • Keep the aperture constant to force the depth of field the same between shots.
  • ISO bracketing is ok as long as you keep the jumps in ISO below the level where noise is introduced by your camera.
  • Exposures closer together will allow you to generate better HDR’s as long as the subject matter doesn’t move.
  • More component images mean more data to  build a better HDR image.
  • Take notes in the field as you shoot so that you can remember what your intentions were at that point in time!  This will help you when you build the HDR.

Some notes on the software:

  • HDR conversions require image editing software that can process in 32 bits.  This means that unless you purchase HDR stand alone software like Photomatrix Pro you MUST use Photoshop CS5 or CS6. Elements and Lightroom simply will not work.
  • I do not like over cooked HDR images.  I process them to a natural look and feel, close to what I can see with my eyes!
  • CS5 & CS6 both include an internal HDR conversion filter called Merge to HDR Pro for free.
  • The NIK HDR software, HDR EFX Pro and HDR EFX Pro 2 require a 64 bit operating system and the appropriate 64 bit CS5 or 6
  • Photomatix Pro is a stand alone filter that does NOT run inside of Photoshop and will allow you to save a 16 bit HDR converted image that can be opened in Elements.
  • All of the conversion software will cost between $100 and $200.
  • I am not going to take you step by step through each of the HDR conversion packages.  This is HIGHLY SUBJECTIVE and no two photographers will get to the end results via the same path!  There a quite a few good books out there on this!

Photoshop CS6 Merge To HDR Pro

This HDR program comes built into Photoshop CS6.  It is quite powerful and gives you a lot of options.  I found it very easy to use and it gives very nice results.  You will find it under the FILE > Automate menu and it  will ask you to locate and open your component images or add images already open!

Once your images have been chosen, it will open them and drop you into a full screen dialog where you can make any image adjustments.  Once done the software will drop the finished image into Photoshop where you can then do your final tuning with Nik’s Color EFX Pro 4.  I like to use the Tonal Contrast filter due to the ability to adjust color contrast in the Highlights, Midtones and Shadows separately from each other.  This one tool will really bring out the full potential of your images.

Here is my version of the three component images processed in Photoshop’s Merge To HDR Pro:

X-Pro1-3495 3496 3497 -Glade Creek Mill -2012 -M to HDR Pro

Here is my version of the three component images processed in Nik’s HDR EFX Pro:

OK, onto Nik Softwares HDR EFX Pro.  This is the first version that Nik offered earlier this spring (2012)  It has a great interface and does a pretty good job, but requires a little more fine tuning after the HDR conversion is finished.  The tuning process was again done using Color EFX Pro 4 and Viveza 2.  This is a plugin filter for the Photoshop family and requires that you run a 64 bit operating system in Windows or OSX.  It will NOT run on Elements and Lightroom.

I found that the images to be a little flat and lifeless until I applied the Color EFX Pro 4 in the after process tuning steps, then the images started looking pretty good.

X-Pro1-3495 3496 3497 -Glade Creek Mill -2012_NIK HDR EFX Pro

Here is my version of the three component images processed in Nik’s HDR EFX Pro 2:

OK, now, this is a MAJOR upgrade to Nik’s HDR software.  This one revision corrected all of my complaints about flat and lifeless images!  There is VERY LITTLE fine tuning needed at all.  I think that Nik’s HDR EFX Pro 2 is my favorite conversion tool out there.  But I will let the images speak for themselves!

X-Pro1-3495 3496 3497 -Glade Creek Mill-2012 NIK HDR Pro 2

Here is my version of the three component images processed in Photomatix Pro ver : 4.2.3

Photomatix is likely the most popular HDR conversion package on the market.  It cost around $150 and does NOT require CS5 or CS6 to run.  It is a standalone system and when it finishes it will directly save a 16 bit version of your HDR image on your computer that you can then open for further editing.  It has many recipes and adjustments and you can do great work with it. I highly recommend it even if you are already running a 64 bit operating system and CS6. You will not be sorry!

X-Pro1-3495 3496 3497 -Glade Creek Mill -2012 -Photomatix Pro HDR

As you can see, the 4 converted HDR images are not at all the same.  That would be difficult if not impossible to achieve.  Each software package has its own adjustments and none of them are exact.  I like Nik’s HDR EFX Pro 2 and Photomatix 4.2.3 the best.  They are all easy to use and as long as you properly evaluate the scene that you are trying to photograph and properly choose the exposure values of the component images you will get really nice HDR shots!

What do you think?  Please let me know!

Updated Grist Mill & Covered Bridge Gallery…


Major Image Gallery Update

I have just updated the images in my Grist Mill & Covered Bridge gallery in the menu on the top of the page under galleries!  I added about 25 new mills and bridges plus provided name and state data under each image!  I hope that you enjoy them as much as I did in creating them!

There is something especially pleasing about mills and bridges that can transport me back to a different time and age!  I will literally  travel hundreds of miles out of my way to visit them!  In 2011 I spent 3 weeks visiting 19 states on the eastern seaboard doing just so, plus this year in May, I spent several days exploring the mills and bridges of south central Georgia!

You can visit the updated gallery by clicking on the drop down under Galleries in the top menu or if visiting from off site click on the link below:

Georgia Grist Mill & Covered Bridges with the X Pro 1


A Few Hidden Treasures…

Starr’s Mill, GA

BW Auchumpkee Creek Bridge, GA

Well my wife and I spent a day exploring the counties north of Columbus Georgia on Thursday looking for covered bridges and grist mills!  We actually visited 2 bridges and 2 mills but only one of the mills was really worthy of any type of photography (more on that later…)  All in all a very enjoyable day!

GPS Track of this trip. Yellow Pins are Mills and Bridges!

I will drive hundreds of miles out of my way to visit a Grist Mill or Covered Bridge and today was no exception.  We left Columbus early and drove about 150 miles in a large circle to hit these 4 locations.  There is just something very special about these old landmarks don’t you think?  I still have about 15 more mills to visit in Georgia and around 20 more bridges!  We have 2 more trips planned this year there, one in August and another in September.  If I can capture 4 or 5 good locations then it will be well worth the time and money to visit them!

Galleries Are Here!


The Gallery pages are coming online!

Sunrise on Folley Beach, Light painting on the driftwood with a white LED light! Very LONG Exposure...

 

On the top menu of the blog you will find several pages listed across the top.  The one labeled Galleries is actually a series of drop down menus which will let you select several organized image galleries containing my favorite work from over the years.  So far, I have 4 galleries populated but will be expanding over this month to around 15.  Please stop by for a visit and come back often to see the changes there!

I hope that you enjoy viewing them as much as I enjoyed creating them!  They cover about 15 years of my work since living in the Low Country of South Carolina and cover about 19 different states and 6 different countries! I even have some high speed water drop photography thrown in as good measure.

The Great South Carolina To Missouri Grist Mill Trip, Day 1


16 Mills in 4 Days!

A beautiful mill full of photographic possibility!

Murrays Mill, NC

I needed to visit my parents who live in St. Louis as they have moved into an assisted retirement home and were selling their house!  They wanted me to take some furniture back south to my kids so that they would have something to remember them by and assist a little with the house in general.  The entire process was pretty painfull and stressfull except for the 2 days of travel at each end of the trip!  For those 4 days I was in heaven!

Bost Mill, NC

I have 173 grist mills programmed into my GPS in the truck that covers every state from Florida north to Boston then west to Missouri down to Texas!  I had no specific stoops planned except for the Glade Creek Mill in West Virginia (which I have been wanting to visit for years) SO… I pointed the GPS to Glade Creek and then went to my Favorites section on the GPS which told me how close I was at any time to specific mills which I could then simply touch and direct the GPS to take me to as a VIA Point!  Using this process I managed to visit 16 mills and could have made 20 or so but it was simply too much to do and still have time to sleep!

Linneys Mill, NC

I spent a lot of time in North Carolina as there are just so many mills there to visit.  Some are totally useless as photographic subjects but still could be saved.  I skipped those that were in such condition along my route. I also would stop at a pretty barn as well but my priority were mills!

Several of the mills along the way were actually working mills that ground corn in order to make a living!  This style of mill is not nearly as pretty as the older 1800’s version but can still be very interesting!  The Linneys Mill in North Carolina is one such mill and very much worth the effort to find and photograph!  It sits along a very pretty stream that has been damed and if viewed from the back is a worthy photographic subject!

Linneys Double Metal Wheel!

Mitchell Mill, NC

Aside from the occasional commercial mill and tons of old mills there are quite a few of old mills that have been converted to private homes.  I especially like to visit these as long as the owners try to keep the exterior the same as designed!  The Mitchell Mill in North Carolina is one such mill and the owners have even kept the mill workings operational!  They were not home when I visited and I really did try to talk to them but alas I was only able to make friends with their three dogs before shooting the mill!  Perhaps the next time I go thru I will stop and attempt to visit them again…

Glade Creek Mill, WV, B&W

OK, it is time to visit the Glade Creek Mill in Babcock State Park in West Virginia!  As I said before, this one mill has been on the TOP of my wish list for several years and the point of my chosen route to St. Louis.  I really didn’t know if morning or evening would be better for shooting here so I kept my options open and planned to stay at a local hotel in case I needed a morning shot!  I needn’t have worried though as I actually arrived at 6 pm and the light was perfect, the fall leaves stunning and there was serious water flowing along the creek and over the various water falls!  There were about 50 photographers there and I had to wait for the locations I wished to shoot from.  I shot both in Color and Infrared but really Color was the priority due to the Fall colors.  I used a Canon 7D body with the 24-70 L f/2.8 lens and a Singh Ray 8 stop Vari-ND filter to slow the exposure way down and allow for soft creamy water motion.  Of course I shot on a heavy tripod using a remote shutter release and mirror lockup!

I processed all of my Color shots for B&W as well.  I also kept HDR in my mind as I setup and shot several sequences for later processing using the new Nik HDR Pro software!

Here are a selection of my favorite images of the Glade Creek Mill:

Glade Creek Mill, Single Shot, 30 second exposure!

Glade Creek Mill, Landscape, High Lighting The Waterfall

Next, a 3 shot HDR image using Nik’s HDR Pro Software:

Glade Creek Mill, 3 Shot HDR, Nik HDR Pro

Glade Creek Mill, 7 Shot HDR, Photo Matrix Pro Software

As you can see, the two different HDR versions give drastically different results.  I like both but can NOT decide which is best! Perhaps you can help with this?

Glade Creek Mill was a dream come true for me and while there are several more world class mill shots coming in the next 3 postings, it was the highlight of my trip.  It was worth the extra miles I drove to include it in my trip and the evening proved the best time to photograph it. I did make several discoveries while at Glade Creek, the most important is that I needed very GOOD ankle high boots in order to safely climb below the water falls and negotiate the rocks!   I did not get a local hotel but chose instead to drive much further on for the night before I stopped.

My next post will be a few mills that I saw on day two!

Stay tuned!
