Orthochromatic emulsions would be a lot easier to deal with than
panchromatic ones, since we can use deep red light. I also found a
couple of dyes that I can buy through laboratory supply companies for
orthochromatic sensitization. I'll be playing with this line of idea
pretty soon. (But I'd love to see infrared plates more than
orthochromatic plates!)
I don't know about Tri-X Ortho. Does anyone have spec sheets scanned
into a PDF or something?
