How can I eliminate glare off polished wood?
Kia Ora
My friend has a lovely carving of praying hands in medium dark polished wood. I have tried all types of lighting conditions but cannot eliminate the shine off the wood. I am unable to treat the wood itself, but is there a form of indirect or diffused light that may not spoil the photo of this carving my friend has made & we are so proud of? Any help would be appreciated. I am using a Ricoh digital camera. Thanks Mac |

Thanks Mac First possibility -- shoot through a hole in a black panel, so no light is coming from the camera; supply all light from the sides (out of field, of course), very diffuse (broad source light behind a muslin sheet, frosted plastic, etc.); that should show up the relief of the carving with little or no glare from reflections into the lens. Alternately, one to three point sources to the side, still shooting through a hole in a black panel, might give less glare if the relief is high and reflects the diffusers into the lens; instead of broad areas of glare, it will then be reduced to an array of points. Either way, be sure to use either enough light or a camera mode that will turn off any on-camera flash, to avoid direct glare. -- I may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E. J.

My friend has a lovely carving of praying hands in medium dark polished wood. I have tried all types of lighting conditions but cannot eliminate the shine off the wood. Traditional way is to use crossed polarizers to eliminate all reflection: o one polarizer filter on the camera o one sheet of polarizer on (each of) the light(s) o Replace the subject with a mirror o Fix the camera polarizer (without camera) to a stand with tape so you can look through it; put a dot of tape etc. at the top of the polarizer ring. o Turn the lamps on one at a time and rotate the polarizer sheets on each lamp so when looking through the camera polarizer (at the lamp reflected in the mirror) the lamp light disappears o Mark each sheet of polarizer so adjusted with a dot at the top. Fix them to the lamps. o If you have hot lights (i.e. not flash) then you can look through the camera polarizer and twiddle the lamp polarizers to add 'just the right amount' (ha!) of highlight. o Put polarizer filter on the camera lens and adjust so the dot is at the top o Take pictures Sometimes just using a polarizer on the camera will be enough. I am unable to treat the wood itself There is a spray just for this purpose called dulling spray - make sure it is the temporary stuff! - you spray it on and it comes right off again with a Kleenex. You may not like the effect. Available at theatrical supply houses or large photo stores. but is there a form of indirect or diffused light Try the biggest, best and cheapest diffuse source: outside on a grey day. Try moving a sheet of white cardboard around to reflect light up into the dark spots on the sculpture. This reflection technique should also be used if you are using the artificial light method, above. Use a lamp (a friend with a flashlight will do) to create highlights. Also: Try a sunny day, put the sculpture in light shade, and move large pieces of white card, aluminum, etc. around to reflect in a little bit of sunshine. I am using a Ricoh digital camera You may need a circular polarizer, or you may not. If it is the usual type of digital camera you may have to use sticky tape to hold the pola filter to the camera. If you rotate the camera from horiz to vert you will need to unstick and restick the filter so the dot on the filter is always up. Any good camera store can supply the camera filter. Try theatrical supply houses for the polarizer sheets for the lamps. -- Nicholas O. Lindan, Cleveland, Ohio Consulting Engineer: Electronics; Informatics; Photonics.
