    Reversal Developing: Re-exposure Question

    Was just wondering if the colour temp of the re-expoure step is important?
    And could I just re-expose in daylight (sun)?

    Regards,
    Peter

    Pete don't take your film out in the sun. I did it once. Got really black film as if it was under developed. I could actually see the emulsion go from a pale straw colour to a vivid yellow and the visible image disappear. Must be all the UV coming through the hole in the ozone.

    As for colour, I have used halogen, warm and cold compact flouros and tungsten lights. I don't feel there is much difference.

    Depending on the wattage I vary the light exposure time accordingly. But about 2mins with film off spiral held up to two 75w tungsten globes which would be 1-1.5m from the film. When using 150w halogen flood I leave the 100ft 16mm film on the spirals and I hold the flood light about 40cm from the tank while rolling the spirals in the washing water to get even light coverage. About 1 min for each 50ft spiral.

    Andy,
    Thanks. I'm doing your test strips tonight!
    Private msg me your email and I'll send a link when I've uploaded.

    Cheers,
    Peter
