Okay, so here is the bent poop from the Desert Photography section of the book, which for some reason seems to have been left out of the later versions of The Negative when the Basic Photo Series was folded into the new series of three books, and I believe addresses many of the issues queried in this thread.
- Moderately strong filters may be justified to overcome the general lack of contrast in desert environments, with the exception of red rock country of the American Southwest. Frequently, because of strong sun and atmospheric effects, contrast will appear to be higher than it actually is. Vast open skies can produce brighter open shadows from reflected illumination. The brilliance of the "high key" light is what defines the desert for many, and I suspect the normal reason to go to DV, and small shadows may be visualized as very black in order to provide important contrast.
- A practical solution is to use filters of moderate strength (NO REDS, unless your intention is not natural light photography), lower your (zone) placements, and expand development N+1, to attain sufficient contrast.
- With respect to specific filtration of the un–red rock desert (where green is highly recommended) yellows can be used. When yellow is employed without applying a filter factor yellow rock will be recorded with almost the same opacity in the negative as if no filter were used. But, blues (e.g., sky) will be darkened to a greater extent than if an exposure factor were applied with normal exposure. If a yellow filter reduced sky values by one zone using normal exposure and applying the filter factor, it might, with normal exposure and no filter factor, further lower the sky values an additional zone. Two, two for the price of one!
For the straight poop, read Adams for yourself and interpret as you see fit!
I happen to have a copy of the Adams and Newhall Death Valley book (my wife keeps buying these books for me at used bookstores in Pasadena) and took the opportunity to review the pictures in it last night. Despite the rather poor printing, one can see examples of application of his technique and visualizations as relates above.
For myself, my normal desires do not include high key visualizations, and seeking storm light in the desert precludes some of Adams' general advice, in these circumstances. I have had very good success with deep yellow filters and N or N-1 development, depending on the light, at Eureka Dunes (i.e., sand and sky). For DV proper this time around, I exposed two negatives at the Artist Palette, one as stated previously, and another including the sky with a polarizer, which worked exceptionally strongly for me for a change. I did not use a yellow filter for true educational purposes and comparing of negatives, at that location. Both negatives appear to be very fine tonally, however, I've learned that the use of the Pyro developer often belies their eventual transferal into a fine print. Shooting in the desert will test your understanding of exposure and printing in a similar fashion to snow, as no where else can.
Sorry I missed you Vaughn.
