Did you shoot this as a test for the collodion shot or just in addition to?Quote:

Kodak/Carestream sells UV duplicating 'wet development' X-Ray film. It is designed for copying X-Ray negatives on a special copy box with UV light source. Big warning on ZZ' site, don't buy for contact printing with WHITE light. My warning is, only insane experimenters should even think about buying and trying it. THIS IS A WARNING. IT MAY NOT WORK. I DON"T KNOW! DON'T BUY THIS FILM!
But what if we used it UV or IR type negative production?

Then this discussion. http://people.rit.edu/andpph/text-in...traviolet.html
And this http://petapixel.com/2013/04/19/a-be...n-photography/
Instructions, notice it produces a positive and exposure to density is reversed from normal film. http://www.wolfxray.com/images/Wolf%...ebea89463bbe2e
I really think somebody must have already tried it!
I taking pictures to Green sensitive X-ray film.
What should I do if I want to dramatic dark sky in the B & W image?
Red filter is not good for this purpose, maybe the yellow?
Wouldn't a simple graduated ND filter work here just as well as anything else? Assuming an open landscape, you are not trying to do anything additive or subtractive to any one color, you are just trying to darken the sky in general.Quote:

Found this info from an eBay seller. It makes sense, but doesn't answer all questions.Quote:

The characteristic curve derived for a duplicating film is the negative slope of a solarization curve; that is, it is different in direction to that of a regular x-ray film. An expired duplicating film is slower than an unexpired duplicating film. Unlike a negative working film, which gains fog past its expiration date, a positive working film (for example, a duplicating film) gains contrast past its expiration date. An expired duplicating film has a narrower latitude than that of an unexpired duplicating film for a useful density range. Clinically, a duplicating film can be used years after its expiration date even though there is a change in its speed and contrast. Thunky K.H. / Weinberg R."

I like the way that lens kind of fades into soft. Nice job, and great exposure.Quote:
