Thanks, that does clear out a few things. I looked up the 2 films I want to use; one has a reciprocity failure past 10 sec, the other past 128sec. So, I guess I'll try to go the enlarger way, with a 80A and a 1 or 2 stop neutral density, wich would bring the neg to an ISO 10 or 20. This should give me a manageable exposure time that might be more consistent. If this doesn't work, then it's pinhole construction time for me!
