    Contrast masking

    Hi everyone, is it possible/feasible to make contrast masks in 35mm for enlarging? Among other problems, I'm not sure how you could get the registration precise enough. But has anyone experimented with this?

    Thanks
    Michael

    I never tried it in less than 4x5, but give it a try and post your results!

    Perhaps someone could make registration pins that have the shape of the perforation. That would simplify things, wouldn't it?

    I've never done it in less than 4x5 either. It seems like given the high degree of enlargement it would be extremely difficult to get this to work. But I have some brutal 35mm negatives (night shots with light sources in frame) that I mistakenly gave normal development instead of compensating development. Luckily, I've been able to make fine prints with alot of work, but the printing acrobatics involved made me wonder if there is anything further I can do to simplify and improve repeatability. I had always considered masking to be pretty much out of the question in 35mm, but perhaps it is worth an experiment.

    Enlarge your negative first? Kind of a pain but it would make things easier afterwards.

    I've never considered enlarging a 35mm negative before. Maybe that would help.

    Geeze,,, Didn't we make paper negatives to do this kind of thing with back in the day? you're stretching my brain...
    Seems like we also used 4x5 lith film in a soft developer to build an internegative... big bloches in my memory...

    don't forget the sub-forum that shal not be mentioned. there are a couple of dry steps that could be added to get back to a more printable negative.

    For this you would almost certainly want to get a pin register setup. Alistair Inglis makes one that works very well. However I haven't tried it for 35mm. Works well for medium format and 4x5.
