    I have some of my dry mounted prints done at school in 1969 and 70. They are exactly in the same condition as the day I made them. That nonsense about not dry mounting prints has been foisted on...

    Re: Nikkor-T ED 1200mm f18 on 8x10

    1200mm on 8x10 is very good. BUT, you’ll never be able to tell unless it’s a windless day AND you have a beast of a tripod. The tripod head has to be a beast as well. I use an old Gitzo (with the...

    Re: ULF Tipping Point

    Pick a ULF size format that uses existing x-ray film sizes so you can pratice with the x-ray stuff.

    Once you go past 11x14 analyze your darkroom to see if your sinks and trays will fit.
