Taken to test a "Fine Grain Positive" material from Ultrafine as paper-speed negative in an 8x10 camera. Paper developer and darkroom safelight.
The negative is very dark but not really opaque at all - it looks like it would take a lot of light to print it but doesn't. I'm looking at this material for a project with pinhole cameras and lots of 7th grade students.
Clarification needed, Mark. There are 54 seventh grade students in the school. I teach them in 4 groups, twice a week. It still gets a bit chaotic at times, but it's not really bad. I just like to make it sound difficult.
