    Default Exposure times

    Hey fellas, I've got my own rig set up, and I've got a 600w halogen 2 feet away from the screen... anyone have a suggestion of how long i should let it burn my screen? Any and all suggestions appreciated.

    If you're using QTX or another fast emulsion, try a test around 20 minutes with an exposure calculator. Otherwise.... 45-1 hour or more? Depends on a lot of factors.

    Need to know:

    -emulsion.
    -positive material.
    -coating style.
    -exposure unit type.

    Do the proper testing by changing only one element at a time, such as the length of exposure. Do a step wedge test or use an exposure calculator / stouffer scale.
