    Finally got the darn thing finished. Not the most practical camera, think my next pinhole camera will be based on existing film holders. I've exposed some paper negatives and the exposures are running in the 20 to 40 minute range. What do I expect from a pinhole that is F380. I have some x-ray film on it's way to play with. We'll see how that works out.

    A yellow filter would work for panchromatic film; for variable contrast => NO. Variable contrast paper is sensitive to blue and green, the yellow filter would do absolutely nothing to change the contrast in the way you would expect ==> It will not darken the sky. If you want to change the contrast with that paper use the appropriate magenta and yellow filters:

    Kodak Grade one filter only
    00.....199Y
    0.......90Y
    0.5....70Y
    1.......50Y
    1.5....30Y
    2........0
    2.5.....5M
    3.......25M
    3.5....50M
    4.......80M
    4.5...140M
    5......199M

    Kodak Grade two filters
    00.....162Y/0M
    0.......90Y/0M
    0.5....78Y/5M
    1.......68Y/10M
    1.5....49Y/23M
    2.......41Y/23M
    2.5....32Y/42M
    3.......23Y/56M
    3.5....15Y/75M
    4........6Y/102M
    4.5.....0Y//150M
    5........--

    These change the overall contrast, but do not darken the sky.

    That's just downright sexy! Nicely done!
