I just realized I could potentially save a thousand dollars or more on a CMOS mono camera by using film with RGB, and maybe even H alpha and O III filters. I am picking up a Canon EOS on Ebay for $50.00 (along with a 400 mm lens!) I already have RGB filters. I do darkroom work, and can develop the film myself. I also have a photo film scanner, which I have used for conventional photography. I figure using Tri-X 400 iso film.
So, I get some subs with each filter, develop and scan the negatives, and then stack them with Photoshop ..right? With ISO 400 film I would need 8 minute exposures for equivalency to 2 minutes at ISO 1600 with a DSLR.
What do you think?
