    Here is my setup, FWIW. All 100w reveal bulbs. You can laugh at my stand, but I like it. All I have to do is move, tilt, or rotate it to show the colors, reduce the glare, etc. My heighth adjustment consists of moving my screw to a different hole.

    Eye - something very important to know when shooting coin pics but it seldom gets mentioned. You only want to have 1 light source. Now I don't mean just 1 light, I mean one type of light !

    For instance, shooting pics when you are using Reveal bulbs and have the drapes open on the windows is a bad idea. Shooting pics say on your dingroom table with Reveal bulbs while the overhead kitchen light is on - bad idea. You cannot mix different types of light.

    When you're shooting pics you only want 1 light source. The drapes need to be closed, all other lights in the room or adjacent rooms need to be off. There can be no other light except the lights you are using to take the pic.

    Then and only then will you get good consistent pics where the color is the same and the right color.

    You see, every different type of light there is causes the color of an object, any object, to change. That's why when you look at coin in the sunlight it looks one color, under a light bulb another color, under a different light bulb yet another color, and under 2 different kinds of lightbulbs yet another color. And there are even more differences between incandescent light and fluorescent light.

    So remember, when shooting coins pics - 1 light source ! You can have 14 lights if you want, but they all have to be the same kind of lightbulb.

    A wise man (dirt farmer turned super successful builder) once told me, "keep it simple, stupid" I appreciate seeing your set up. What kind of camera are you using?

    Point taken, I haven't seen that in any of the volumes of books I have read. I guess it fits under common sense for cameras with fixed white balance? I do have several types of light running, let's see.

    minimal window glare, shades are drawn but there is certainly some daylight leakage through the blinds.
    Television Flat screen Light
    CRT Monitor light.
    Small CFL 25w equiv pointed into closet
    Desk lamp with std incandescent.

    There are a bazillion settings for white balance on this camera, including being able to enter in CFL specs up to 6500k on top of manual .



    I am on (and will be) on a huge learning curve - once I have the camera tethered to a live view/capture, I should be able to set the white balance to match real life to monitor to printer. The Photo Printer is already calibrated to my monitor
