  1. Re: DIY Gas Burst Agitation for 1 gallon vertical tanks

    My original plenum is plastic. I made another from aquarium air line tubing and glued it down to pieces of an under gravel filter to provide the distance above the tank bottom.
  2. Re: How many film holders do you bring for a day out?

    X-ray film has to be learned just as any film does. Used within its limitations, it works well.
  3. Re: DIY Gas Burst Agitation for 1 gallon vertical tanks

    I have a plenum from an old camera store setup for the 3.5 gallon tank. The downward tube ends in a T fitting and the gas tubing in the tank is a continuous, though zig-saggy loop, not a dead end...

    In the early 70s I was shooting a Yashica TLR when I saw a magazine article on the Zone System. It immediately made sense to me. Shortly after, I saw Adams’ five little books in a store. Reading...

    Re: Grafmatic Back Operation

    That looks right to me. I’d only add to be sure the camera is more or less level front to back when operating the Grafmatic so the springs and gravity can move the septums properly.

    Re: Using filters on LF lenses

    Oslolens, that is correct. Focus first, add the filter, refocus. Or add the filter and focus for a single time. Some say simple gel filters don’t require refocusing.
