I am searching for a routine to do some testing that might not take so much film ...
Normally, I would either know from experience or I would come to a calculated guess as to the film ISO and development time for 'normal' development ('Normal' for me is to the CI of condenser enlargers - 0.47ish). I would shoot a roll of 35mm film in my Nikon of various exposures from -4.5 stops to maybe even 8 stops over my 'N'. I would then develop for the guesstime time and repeat for N-1, N-2, N+1, and N+2 etc. This would involve a roll of 35mm film for each development time and I'd like to have one sheet of film take the place of a whole 35mm roll basically.
I am trying to get an understanding of how to do it with a 4x5 step tablet and no enlarger. I do not have an enlarger nor do I have access to one.
If I jam the step tablet and a fresh piece of film into a holder and then use the camera as an exposure tool, could it be done? (Can a sheet film holder accomodate two sheets without damage?)
Do I just keep firing off a few sheets till I get most of the tones on the tablet onto the film at the guesstimated development time? From there I would then shoot off say 6 sheets to develop them differently?
It all seems rather haphazard...
At least with the Nikon I'd know the shutter speeds used for each exposure...
