  1. Re: mounting gelatine filters between glass

    Sounds to me like a quick tutorial and some practice with cementing glass, filter, lens elements together is in order. Get some scrap glass and filters and some lens cement and "go to school" and...

    Re: Vitamin C developer for paper

    If I'm not mistaken, the OP is making paper negatives, not prints, so the solution he's using to develop with may not work well for making regular enlargements.

    My pleasure.

    I believe you are right about the cover glass not affecting focus. I can't see how it would. Maybe someone here has their cover glass at hand and owns a caliper and can give us a...

  12. Re: Marks and spots on my almost dry negatives
