how to eliminate glare Need to photograph about 400 items encased in clear epoxy resin. Epoxy is poured over photographs so the edges of the epoxy is curved (i.e. not square off). All lighting used to date creates glare (flash, tungsten bulbs @45 degree angle, overhead fluorescent, shaded sunlight). Tried--polarizer filter on camera, black posterboard to block light causing the glare, and all of the different settings on the HP 945 digital camera. At this point I am open to most suggestions. I am seeking an economical solution if possible because the photographs are for a small startup business. I thank you very much for any and all responses. R. Hubbard

Maybe something like a cotton sheet or the like to attenuate the output of the light. Seems like less potent light plus a longer exposure time could work. I think back to the table lamps with a shade: when you remove the shade the light output is quite glaring, but when you put the shade back on, there is still light, but not so overwhelming. I am no expert.......just and idea! Loren Roque

Hi Rayford, Somethings to try would be to use a softbox or heavily diffused light to illuminate the item. Glare is caused by the reflection from harsher light gathering because of the curavtures of the epoxy. That can't be filtered out through polarization(only filters out light at particular planar angles) or filters(cuts certain bands of light). My thought is that if the item is not too large, try a cloud dome or a diffusing tent around the item and then illuminate from the outside with diffused light. That should result in the least amount of glare off of the epoxy. The other possibility would be to coat the epoxy item's surface with a clear matte finish to reduce reflected glare. Can't really be more specific without knowing what the item looks like. :) But I think the answer to your quandry lies in diffusion of your light source through a dome/tent. Good luck and please post before/after pics, if you manage to get rid of the glare!

Glare is comes from the angle of the light instead of being diffused or direct. An ideal set up would be to have two flashes at obtuse angles, and shoot thru a hole of black fabric or black cardboard so you won't get a reflection of yourself and the camera, and also the wall or ceiling in the resin coating. Making copy prints of high glossy photos presents the same kind of problems. You can minimize the reflection of yourself in the resin if you use a longer lens, instead of trying to shoot with a macro, if that's what you're using.
