    Default Another Ghetto Exposure unit.

    Taken from Gwen Gibson's site. I bought some of her photoEz stuff.

    Build a light table








    What you’ll need to make the light table
    Light fixture: Two 20-watt double fluorescent light tube fixtures measuring 24" long with cords and plugs. (If you don’t want to re-wire the fixtures yourself, ask if the store will re-wire up them for you).
    Bulbs: All of the following tubes will work, but the exposure times vary.
    Fluorescent Light Table Exposure Times
    using two 20-watt bulbs approximately 1.5"-2" from PhotoEZTM
    Full Spectrum tubes Transparency 4 minutes
    20-lb white paper 14 minutes
    Daylight tubes Transparency 6 minutes
    20-lb white paper 24 minutes
    Cool White tubes Transparency 14 minutes
    20-lb white paper 40 minutes

    Clear Top: Plexiglass (1/4" thick) for top measuring 14” x 28”
    PVC pipe framework: Two 12.5" lengths 3/4" pipe for short sides of table
    Two 25” lengths 3/4" pipe for long sides sides of table
    Four 3/4" x 3/4" x 1/2" side outlet elbows with a 1/2" threaded opening for corners
    Four 4" lengths of 1/2" threaded nipples for legs
    PVC piping comes in various lengths and will probably require cutting. If your hardware store won’t cut it for you, you can purchase a ratchet action PVC pipe cutter that cuts up to 1” diameter pipe for under $10.

    Total cost of materials to construct the frame is approximately $21.
    Light fixtures and bulbs are additional.


    Assemble the light table
    Insert 2 long pipes in outlet elbows.
    Insert 2 short pipes in remaining openings of outlet elbows.
    Insert threaded nipples into threaded holes in outlet elbows.
    Place over top of PVC frame.
    Place the clear plexiglas sheet on top of the PVC frame.
    There should be approximatly 2" between the plexiglass and the bulbs.

    You can modifiy to fit your needs.

    That's a nice simple ghetto setup. You could probably even add some reflective walls around it to keep the light in and aimed at the screen. Looks like you might be losing quite a bit of light out the sides. Good work.
