i know for a long long time orth-based film emulsions were king.
roll film, plates, and sheet film were all ortho.
now, unfortunately there are only a small handful of ortho films out there ...

would it be less expensive ( not b/w dyes needed ) to have ortho film made
rather than now-traditional pan-film?

i really like the look of orthochromatic emulsion, and would love to have choices
other than lith film, or paper negatives.

i have coated film base with bottled emulsion before, but my efforts
were not very successful.
