I have shot kodalith in my 4x5 for portraits, so that the kids involved in the project could see the latent image in the negative come up in the developer tray.
I rate this film at 3-6iso in this situation.
To shoot at f/8 it was 2- blackline heads with 11" refectors at 4' , with 1200w/s dumped into each head. The sitter could feel the heat on thier face when the shutter was tripped.
I hate to think of the abuse on the flash tubes that this project contemplates.
