I bought a halogen desk lamp as suggested in another post I read. I am having a couple problems.

1. I am having trouble with too much glare on high points of silver coins. I have played with white settings on camera and different exposures but with little success. should I be trying a soft white bulb?

2. The halogen generates alot of heat...I read that the light should be positioned directly over coin. This is hard to do , even with smaller desk lamp I can't seem to get close enough to lens.

My camera is a Sony dsc-w70 7.2 mp but I only seem to have 5 preset white balance settings. Incandescent seems to be the best but I still can't get those nice flat images with shiny silver.

Should I try a second desk lamp and keep them farther away from the coin?
Any suggestions?

Thanks

Sounds like you might need a light diffuser to soften the glare. I haven't tried a "soft light bulb", but sounds like it's a good direction to try.

Don't let the blue bulb freak you out, it's about the whitest light you can buy.

Oh, and wait till you see the shutter speed your camera picks for these bad boys. You could take the photo with the camera hanging around your neck while doing jumping jacks.

Be warned, they also burn very hot. Also, they only last about 3 hours total "on" time.

You could freeze-frame a tachyon with that bad boy.

Even at 1/3200, f8.0 and ISO 50, the best my S2 can do, I bet it would still look like I was taking a macro shot of a lit streetlight if I ever tried to image a coin with that portable sun.

Pending the weather try taking photos outdoors. Not in direct sunlight though. If you have access to a black car, black bar-b-que, etc. place a coin on that serface outdoors, not in direct sunlight. You save on all sorts of electric bills, get great photos and not have to run all over to stores for special lamps, bulbs, stands, etc.
