I make enlarged b&w negs from colour slides on panchromatic b&w film (e.g. tmax). Works nicely. Easy.
Hopefully these aren't silly questions....but:
1) To get proper exposure, could you possibly just meter the enlarged image on the easel (white) and get proper exposure?
2) Is it possible to use a color head to have more contrast control?
Keith, how do you meter those exposures, or have you gotten to a point through trial & error where you just know where it needs to be?
I had the idea of taking an incident reading at the baseboard using the ISO of the panchro film, and using the exposure time at f/1.0.
I intend to do just what you've described in the future and any way to minimize film wasting would be good (for me at least... )
Yes, I suppose that you could, but what I do is just sacrifice one piece of film and make test strips from it. And then I determine optimal exposure and development just like I would for paper.
Not for contrast control. It won't work like MG paper, if that's what you're asking. But there are many other ways to control contrast, e.g. by fine-tuning exposure and development, by dodge and burn, by bleaching and SLIMT (which I haven't done, but why not). Colour filters will allow you to play with with tones correspond to particular colours, so a colour head will be nice to play with (I don't have one).
Not sure why you'd pick f/1, but otherwise it sounds good.
