Building Photographic Websites
I make websites for artists and photographers and find that most folks need some sage advice on the process...
 

I use Dreamweaver, CSS, PHP and MySQL to do websites and I don't recommend trying to do your own if you want to have dynamic uploads and e-commerce sales. The computer science part becomes overwhelming rather quickly.

I have seen some nice sites using frameworks that are available via commodity web hosts like Joomla and Drupal. I have not tried deploying one of these skeletons but I will bet there is some skilled labor in there somewhere.

There are two types of sites, active and static. An active site uses a database and a serverside scripting language to enable you to have blogs and galleries with uploads. Static sites require you to edit the page to add anything to it.

Blogs are very important as they provide lexical "fish food" for the spiders. A spider is an application that reads web pages for inclusion in the search engines. They read text and not pictures so accompanying pictures with a good chunk of descriptive text will get you better page rankings. The page title and the description meta tags figure prominently into the page ranking formula.

Have a look at my gallery pages to see this concept at work.

I am working on integrating social media and blog sharing and am getting good results so far. I have a Facebook share link on my Free Desktops page and give the deep linking code with a link back on the large image page.

I am getting good incoming linkage off of this program. Last time I looked I had gained 400 incoming links from posting the deep link code. In that past I had tried to hold tight to the work and that is a path to an epic fail. The rules have changed and we must change with them. I have yet to build an AJAX widget to get metrics from the Facebook sharing but I will get there. Building a good site is an incremental process.

Flash is a dead horse in that respect as it does not spider well if at all... The page ranks of flash sites are usually very low. If folks can't find you then all is lost.

If you want a static site Google "Free Website Templates", pick one that you like and have at it with Dreamweaver or one of the free HTML editors. I have done many sites with free templates and get a good result but there can be a certain level of CSS adjustment and debugging that needs to go on with them. It is good to use DW's File->Check Page->Browser Compatibility and the W3C online compliance checker before investing too much time in a template.

If you have a wedding or portrait studio and you don't have a web site get one now as you are losing money and working way harder then you need to on the proofs and ordering.

If you do fine art it is better to start sooner then later but don't expect a gusher of money. It will pay off in the end but you need to do the work.

If you know a geek try to work with them as web technology, while it seems simple, is very complex and you will take some lumps going it on your own. By the same token beware of folks selling snake oil for big bucks and shop around. If you pay someone you should get a very nicely designed active site in the 1500.00 to 3000.00 range.

Of course this is all IMHO :) 

If you want to chat with me about a site call me at my studio 10-6 PST (510) 742-0548. 


Workflow from Camera to Print
How I manage my files from image capture to output
 
Here I cover the different types of files, RAW vs JPEG, bit depth, layers and output formats that are in a digital photographic workflow from image acquisition through output.

There is a fair level of confusion as to how you should manage your data. If you do not do so wisely you will end up storing way more data then is necessary. I cover the problems of data storage in another posting.

I start with camera RAW files and convert the ones I will edit into multi-layered 16 bit Photoshop files.

These files are then adjusted, proof printed and sharpened. When a master is to be printed it is flattened into an 8 bit single layer of data. The image is then resized without resampling to get the desired print size or if the print size is out of range it is up-rezed to get a reasonable amount of resolution.

This allows for the print output files to be retained so that if the last print was a pass then the next will be as well.

I got a new film camera, the Gaoersi 617
Direct from Hong Kong
 

I got the Gaoersi 617GF camera direct from the manufacturer and have been using it with a Schneider 90mm f8 lens.

Because of the width of the format, 6 ½ inches, it is necessary to use a center graduated ND filter to correct for the fall off. I got the Schneider filter to be sure it was correctly graduated.

This filter steps the 67mm front thread up to 86mm so I had to get an 86mm Polarizer, Skylight filter and WA lens shade.

Once I got through all that I shot the first 15 rolls of film. 4 shots per roll.

And… All good!

The camera is tight, well made and at slightly over 1000.00 delivered it is 9000.00 less then certain overpriced German boxes.

I added a polarizer to the viewfinder to allow me to set the polarization angle on the taking lens. I did it with adhesive putty so far but will ultimately glue on a stepping ring because I usually use a polarizer.

The Center ND is worth 1.6 stops as is the polarizer so that makes the shutter speed a little low with 160 film. Some people say you have to shoot at 22 or greater for good coverage. I have yet to test that wives tale but will soon…

I got the hyperfocal distance chart direct from Schneider and it seems correct.

At 10' focus I get 4.5' to infinity at f32 at 15' focus I get 15' to infinity at f22.

You do have to focus by the numbers as this is a rangefinder camera. Focusing is via a helicoid movement in the lens cone. I calibrated and made a scale for mine as you really need to know the focus distance.

This is a camera for skilled operators. All metal, all mechanical, all manual.

It takes a little setup for your lens but I had no problems getting the infinity focus set properly. I got the Fotoman focus document and it was informative.

If you do large format or pro film photography you will get this camera instantly.

At this point I am totally happy with the Gaoersi 617 and will shortly have some pics coming up in my galleries from the negatives.

I will add the links to the pictures to this post sometime soon...


Camera Settings for Digital Photography
How to set your digital camera to get the best images possible
 
Digital cameras have too many settings and modes. It is all to easy to have a setting that makes images that are not right in the end and are difficult to adjust and sharpen when you try to take your picture past the snapshot stage.

Here are the basic settings.

ISO to the slowest speed, this makes for minimum noise Sharpening OFF Color Enhancement or Vivid Color OFF If resolution is a setting set it to the highest number of megapixels. Set the file type to RAW, TIF or DNG, these produce 16 bit files. Set the white balance to match the lighting conditions.

I have the reproduction curve on my Nikon set to AUTO and it has not been behaving badly. Mainly you want a setting that is not pushing the tonal range and contrast too far in one direction or another.

My theory is to get it all on the file and bring it back to the lab where I can adjust it interactively. With interactive adjustment it is not a question of previsualization of the scene at the time of exposure. It is a revisualization at the computer where you make the adjustments that you felt were necessary based on the experience at the scene and the wisdom of 20-20 hindsight.

I try to not get locked in to odd color balances, saturation enhancements and extreme contrast curves at the camera level because all of these functions can be performed in post at a color corrected monitor rather then on a windy hillside.

Filters for Color Digital and Film Photography
Use these filters to improve the color and rendition of your photographs.
 

For general photography in digital or on film there are several filters that are most frequently used to improve the rendition or alter the possible range of exposure values.

Make colors snap…

If I had to have only one filter it would be a circular polarizer. I use the polarizer on most of my nature photographs.
The only time that I do not use it is when I am photographing rainbows or handheld in low light. When photographing reflections the filter does not need to be removed just rotated to the correct orientation so that you get the desired degree of reflection. This can be useful in controlling the amounts of reflection from bodies of water as some reflection is nice but the natural amount is usually too much. Rainbows suffer from the polarizer and it must be removed to fully render the rainbows subtle colors.
The polarizer will darken the sky a variable degree depending on its setting. Plants will be rendered with richer colors because the polarizer cuts the specular reflections off of the moisture in the leaves. Most colors will benefit from the polarizer’s effect. This is different from turning on the vivid switch in your camera. In-camera processing is always a bad idea as it is better to enhance color saturation and sharpness interactively in post processing.
The exposure compensation for a polarizing filter is +1 2/3 stops. This has been standard across all the polarizers I have owned over the years.

The second filter I carry is an ND or neutral density filter. ND filters are marked with the opacity value as if they were being read on a transmission densitometer. .10 is 1/3 of a stop, .30 is one stop and .90 is three stops. I like the ND .90 as it gets me into a different range of aperture and shutter speed combinations.

Making the water move…

If I have two filters the second is a neutral density filter. At EI 100 the BDE, basic daylight exposure, for direct sun is 1/100 at f16. As many lenses only support f22 as the maximum aperture this makes the slowest shutter speed available 1/50 (at f22).

Good movement in flowing water happens at shutter speeds between 1/15th and 1 second. 1/15th gives you lots of texture and good movement. As you head towards 1 second the water becomes less detailed and more unsubstantial. At about 5s the water seems to be simply a cloud in the channel. With the preceding assumptions you will see that using a polarizer with its 1 2/3 stop compensation factor will give an exposure of 1/30 at f16 or 1/15 at f22. You are exactly at the top of the range of good motion effects.

Using the ND .90 and the polarizer I get an exposure value of about 1⁄4 at f16 or 1⁄2 at f22. This filter allows me to really hit that window of good motion that happens between 1 second and 1/15th second and to have some choices as to how I want to render the water rather then just being stuck at 1/15th at f22 with the polarizer.

I find that the ND filters will change the white balance of the picture slightly and I have a custom white balance that I use for the filter. This amount of color shift is certainly not much and can be easily corrected in post processing.

When you use more then one filter the old wives tale is that your focus will suffer a very small amount. I do not feel this is even noticeable and will not hesitate to use the second filter, especially as you cannot get to this range of exposure values without it....

The third filter is the UV0 or 1. I use these to protect an exposed front lens element. As I rarely remove the Polarizer this is only for that time. A good example is photographing in low light where the polarizers density makes it too hard to see through the camera and there is not a direct light source to produce specular reflections.

It is critical that whatever filter you are using that you use a lens shade. This prevents lens flare, which robs your pictures of contrast and color saturation. Unlike the difference between 1 and 2 filters, which I cannot identify in a photograph, I can usually tell you weather your picture was shot with or without a lens shade.

I use a lens shade and my fedora type hat, which I hold over the lens to cut that last bit of flare when looking into the light. If you look at most pictures of Ansel Adams working you will not that he is wearing a fedora, there is a reason for this…

When the wind conditions are to high for me to wear the fedora I carry an 8x10 piece of black mat board that I use as the additional shade. I cannot stress too much the importance of a good lens shade and making the extra effort to do some additional shading. You can usually see the effects of the additional shading in the finder because it really makes a big difference.

Basic Daylight Exposure (BDE) Calculation
For outdoor photography the light meter is not always your friend...
 
Most mid-day outdoor photography includes areas illuminated by direct sunlight. If you have elements in your picture that have direct sun falling on them the correct exposure is really a foregone conclusion.

If you find the BDE formula in an old photographic technique book it reads like “The reciprocal of the film speed at f16” a terse and potentially confusing statement of a simple calculation.

If you set the film speed, E.I., as the shutter speed and put the lens on f16 you will have the correct exposure for bright sunlight.

With film speed (E.I.) 125 the BDE is 1/125th at f16, E.I. 400 is 1/400th at f16.

But you use your light meter and it gives many different readings in the same situation.

Which is right? Only one… The BDE.

Your camera is averaging the values together and calculating the exposure. If you have direct sunlit areas in your picture they will be over or underexposed by an averaging meter.

If I want good exposure in bright sunlight I calculate the exposure, set it and forget it. I ignore the meter because it will lead me away from the path of righteous exposure.

Many famous pictures were shot using this methodology including “Moonrise over Hernandez N.M.” by Ansel Adams. In the case of that image he used the known standard amount of light on the moon to calculate the exposure. He frequently used this as it is always correct if you have direct sun on some part of your scene.

This method won't work for sunrises or sunsets but... for the rest of the day it is rock solid and dependable.

Try it… It will free your mind to concentrate on the picture rather then getting the correct exposure.

Film Speed Table
A table of film speeds, E.I.'s in 1/3 stop increments.
 

Knowing the film speeds can be useful in applying filter factors and making general exposure calculations. Following is a listing of the film speeds (E.I.'s) in 1/3 of a stop increments.

To calculate the exposure correction for a filter simply take the amount of in stops and subtract that from the E.I. using the table below and then use that re-calculated film speed to make your exposure calculations.

To convert from filter factor to stops is a little less clear. A factor of 2 is a one stop increase, 3 is 1.5 stops and 4 is 2 stops. As it goes on 6 is 2.5 stops and 8 is 3 stops.

I always calculate the correction values of my filters in 1/3's of a stop not factors. Filter factors are the construct of a warped mind and are an unnecessary level of distraction and indirection.

No, no attitude… I really do love filter factors. /snark

It is just more direct to make a correction without having to calculate the factors difference in stops prior to making the correction.

Mark the correction amount on the filters case or some tape on your filter pouch. I call the thirds .3 and .6 so that a correction of 1.3 is an increase in exposure of 1 1/3 stops, 1.6 is an increase of 1 2/3 stops. Using this method a P1 circular polarizer has a correction of 1.6 stops.

Bellows Extension Calculator
Online bellows extension factor and exposure compensation calculator and printable exposure compensation scale
 

Here is a quick way to calculate the bellows extension factor and exposure compensation amounts for large format view camera users in the studio.

To use the calculator follow this link.

Online bellows extension factor and exposure compensation calculator...

However when you are working in the big room there is no computer or webbernet so the online calculator is not an option...

For years I have calculated my bellows comp in my head for large format. I always enjoyed using my RB-67 partially because of the bully bellows comp scale which made the bellows factor calculation into a non-issue.

I wanted to improve my large format production rate as it is a notoriously slow process. This was one of the points where I saw that it could be better, not that it took me that long to figure out the factor but just having to go into math mode detracted from the experience of vision and visualization.

I have carried a legal size xerox of a ruler which I coated with packing tape on two sides for years. When backpacking a 4x5 I try to keep the kit light.

I decided to make a scale that was like the RB-67 scale which covered the lenses in my kit while giving me an inch ruler as well.

I immediately noticed that there were not many simple calculators for bellows extension on line so I fixed that...

While I can't use the online version in the field it will certainly did enable me to make an excellent paper ruler.

I first made a 2 inch tall version and hindsight being 20:20 I decided I wanted it even smaller so I transformed it to make a 1 inch version. My Zone VI field camera has a 300 mm maximum bellows draw my ruler ends in that range. The ruler is around 14 inches long.

Here are links to the two rulers, the 2 inch and the slightly more compressed 1 inch version.

Large Bellows Extension and Exposure Compensation Ruler


Small Bellows Extension and Exposure Compensation Ruler

For the mathematically minded out there (not me) here is the formula that I used for the online calculator:

  • extension is bellows extension in mm
  • focalLength is focal length in mm
  • factor = (extension * extension)/(focalLength * focalLength)
  • stopsCompensation = log(factor)/log(2)

Spotting Flecks on Ink Jet Prints
Using Marshalls retouching dyes to remove those occasional flecks
 

With inkjet prints there are occasional spots where the surface flecked off leaving a small white spot. While this happens rarely it usually happens on a larger print.

I guess that is just Murphey doing a really fine job of it!

To fix this problem I use the standard photo retouching methodology...

Marshalls photo retouching dyes take well on pigment inkjet prints and I find that all in all it works fine.

I have a 00000 (5 ought) brush with half the hairs carefully trimmed out and I use a pair of strong magnifying glasses. It is critical that you can see the work magnified.

I have all the colors of the dye dried in the compartments of a plastic palette. I put a few drops of water in the center and dip from the dried color spots to make an even small dot of water with my color match in it.

I test on a piece of the material I am retouching and wear a nylon glove on my left hand so I can touch the work freely.

I try to fill the white spot without overlapping the edges with a medium wet brush. I look for the brush to make a consistant line when gently stroked on the test sheet. If you touch it and it leaves a drop it is too wet and if it wont make a short consistant line it is too dry.

I want the brush to deliver dye the first time I go at a spot amd I may gently touch the sopt several times to make dots that fill it in rather then swabbing at it. Swabbing at the spot is death, you want to fill it with small several gently overlapping dots.

Like anything this is a skill and takes practice.

I would recommend that you make a black file in photoshop with some small white dots and practice on a printout. After you have done 20 or 30 you will get the hang of if and be spotting away...

A big part of success is the few hair brush and the magnifyer so you can really see the spot.

I was fortunate enough to have been able to get some training in retouching in the 70’s and although everything has gotten much better I still find spotting to be a useful abilitiy.

Now those Adams vibrating pencil retouch stations for negatives... Mine perished in a fire and I would much rather photoshop the face thank you :)

But those damn occasional flecks!

Actually we have it easy now because an absolutely clean wet photo print was rare if you were a critical worker, it seemed like everything needed a little touch.

Now I spot my dust once and it is gone-gone-gone and life is good!


Stretching Canvas Photographs
How to stretch photographs printed on canvas with inkjet printers.
 
I have been doing well with prints made on canvas materials.

People like them much better then framed photographs and they are highly viewable as glass-less prints.

However as a photographer stretched canvas was all a mystery to me. I have gone through a learning curve to be able to produce canvas prints. While the requirements for photography is similar to stretching canvas for painting photographs want less tension.

I have been using the LexJet Instant Dry Satin Canvas with their profile on my Photo Black - UltraChrome Epson 9600 and have been getting fairly good results. I find the profile is sensitive to red in the shadows so I tend to be sure my shadows are a touch on the cool side to avoid red in the blacks.

Cooksey-Talbott Gallery is an online e-commerce gallery of nature photographs. The collection includes pictures of the High Sierra, Ansel Adams Wilderness, Yosemite, Trinity Alps, Sonora Pass, Santa Barbara Hills, East Bay Hills and Garin Park as well as hundreds of different waterfalls. Many of the images are from medium and large format film taken with the Mamiya RB-67 and a variety of 4x5 view cameras. Some of the more recent work is shot with a Nikon D200. We offer archival quality prints in a wide variety of sizes and on different media. We print on a variety of heavy art papers and canvas using a Canon iPF8100 44 inch 12 color printer with pigmented inks.

Ralph Cooksey-Talbott Thomas has been working as a photographer since 1972 when he moved to California from Michigan. During the 1970’s he studied under Ansel Adams in Yosemite. Ansel published one of his photographs in the portfolio section of his book "Polaroid Technique Manual." Ansel and Orah Moore, another of Ansel’s students, suggested that he shorten his name to Cooksey-Talbott, and that is the name he has worked under since. Cooksey also studied at the San Francisco Art Institute and the San Francisco Academy of Art. He has lectured in photography at the U.C. Berkeley Extension, Studio One in Oakland and at Santa Barbara City College.
