    Dear BetterSense,

    I would look into an old Speed Easel (sp?). Add a cover with a slot using mat board or the like and pull the paper through after each exposure.

    Last week, I saw an advert for a Kodak Print scale.

    This is a disc with various sections fitted with neutral density filters. The idea is that you expose a piece of paper with this on top for 60 seconds then read off the time setting for the area with the best exposure.

    I am now going to make one of these as I have found some gel ND filters about 1.5" x 3" at 0.5, 1, 2, 3 and 4 stop densities.

    Mine will not be as closely spaced as the kodak version (I think that one is half stop spacing) but it should give me a good idea.

    Mine will give exposures of 42, 30, 15, 8 and 4 seconds from a base exposure of 60 seconds.

    I will post a picture when it is done.


    Steve.

    Lift the cover after each exposure and slide the paper along the edge to the next notch.

    Ralph, I read in your book that you use 5x7" paper of whatever emulsion you're using for the test strip printer. Do you find the emulsions usually match? Or do you have to test once in a while? Some people recommend running test strips from the same box of paper that you're printing from. Thanks.

    Or, an 8x10 sheet cut in half would give 2 5x8 test strips.

    Having used Kodak, Agfa and Ilford paper, I've never seen large deviations from batch to batch, but as paper ages it becomes softer and differences can become obvious. Rather than using 5x7 paper of the same type, it is much better, and not much more effort, to cut 5x7 or similar from the box that you're actually using. I don't recommend the previous practice any longer, and this will be corrected in edition 2.
