  1. Re: How to expose in unusual circumstances


    In your particular situation here, there's nothing stopping you from, say, pointing a spot meter straight up and taking readings of the important tonal elements of the scene. Or, using an...

    Re: Keeping Time tray developing film

    In my apartment in Vienna, I had no dedicated darkroom for almost 30 years. I tray-developed film in a darkened bathroom using a metronome and a digital kitchen timer. The kitchen timer was set for...

  5. Re: Seeking Ideas For Simple 8x10 Contact Printing Solution

    I second the idea of using an enlarger head as a light source. It could be a small dichro head (35 or 67). It wouldn't even need a column, just some way to hang it from the ceiling temporarily when...
  6. Re: Fresnel screen focus distance is different from ground glass


    The Chamonix N-1 was designed poorly; the addition of the Fresnel lens was not taken into account and adding it, while brightening the image and evening the illumination, threw the focus off....
  7. Re: Camera confusion: Beginner Puzzles over Chamonix et al

    Simple answer: In order to keep field cameras light and costs down, they can't have all the features at once (those that do, and there are a few, are bulky and heavy). So manufacturers trim down...

    It strikes me, that the scenarios you present are not "unusual" at all... rather situations one encounters commonly. Metering technique, then, would be standard as well.

  11. Re: Citric and acetic acid as stop (bath)

    Note: Some people use a water bath in place of an acid stop bath. There is still a "stop-bath" step in the workflow; the negative does not go directly from the developer to the fix.

    Re: HC110 B with HP5+ @ 100

    I find the notion that one must reduce development time for film rated slower than box speed erroneous. Developing time affects the contrast gradient of the film equally, regardless of the E.I. ...
  13. Re: Mural Printing: Suggestions for large volume chemistry please!

    Your 150mm lens will work fine for close-ups. How close you can get will depend on your bellows, but even the most compact cameras usually have 300mm of bellows extension, which will get you 1:1,...
