Just testing the water with a pinhole photography project I'm doing with some students next month:
I've got my 4x5" Ilford direct positive paper
made my pinhole camera (kelly's icecream tub and 0.3mm 'pinhole' drilled in copper shim)
loaded it and tried a 6 minute exposure as suggested in the ilford literature
Dev the paper and its black, so i think dam massive over exposure or light leak!
So i do another shorter exposure, results are the same
So i dev a sheet straight out of the box and its black... Now thinking damn its gone 5 I cant even ring ilford to ask for advice
Just dawned on me over coffee, its positive paper, black is under exposure not over exposure!
Maybe tomorrow when my brain is working I'll have another go
