    Here is a technique I learned on another coin forum. It is called coaxial lighting and relies on a piece of glass angled at a 45 degree angle, although I alter it sometimes to eliminate glare. I use a glass front picture frame which I held at the angle with an old piece of surplus clamp. I should go out and saw a nice oak piece, but once i got this working OK, I get lazy. The lamp holder came from the Salvation Army for $1.50. I got paint "chips" from the Home depot so I would have different colors for background. A bright white one for color balance settings.

    This view is looking through the glass from the front. The glass is still tilted back at a 45 deg. angle

    Now with the light turned on

    SOmetimes glare is a problem such as with slabbed coins.

    So I put a piece of tissue between the light and the frame

    And it helps a lot. Probably most people have similar "makings" around their house.

    spock the idea is to diffuse the light. You can do it by putting a milk jug over the light, taping a piece of paper over the light, placing a tissue between the light and the coins - virtually anything white or opaque between the light and the coins will diffuse the light. And that makes for better pics.

    i am afraid of the tissue catching fire if i put it ont he light source. i wonder what i can do to diffuse the light. lets try a plastic handbag over a light source. stay by the phone in case we need the fire department ;)

    The glass in the frame is at a 45 degree angle, leaning towards the light. It should be close to the height of the lamp. When light from the lamp hits the inside angle a portion of it is directed straight down onto the coin.

    Whatever light doesn't get sent down to the coin just goes straight through the glass. No light ( unless you have a very shiney proof or a plastic holder) is reflected up through the glass to your camera. It is called coaxial lighting because the light from the lamp is going down to the coin, and you camera lens points the same direction. It is like your camera is the light source also. The tissue just diffuses the light enough so not much is reflected back into the camera. Hope this helps.

    The tissue isn't placed on the light, it is taped to the top of the frame and drops down "In front" of the lamp ( a few inches away). You could use any diffusion material, like the piece of milk carton, etc. Also, you can move the light farther away, I had it close to slow in a single photo.

    spock sometimes you amaze me :rolleyes:

    If you get a light like this - you tape a piece of printer paper to the shade - not the the light bulb. And it will not catch fire.

    Is the shade bigger than the paper? If not it should bend

    yeah in theory but it is almost touching so there is risk of fire but genius spock has come up with a new method called the museum magnificiento. all in a new thread called NCS part 2 :D

    spock the light bulbs do not stick out of the shade. I have used this method myself, for years - never even scorched a piece of paper let alone started a fire.
