Default Pics behind glass

Any tips on how to take a photo of a picture behind glass without reflections? Thanks.

I've used a flexible lens hood holding it right against the glass.

Thanks donp. I have tried all sorts reading other posts and Steve's page on the subject. I only possess digi cameras and no matter how far away or close I am from the framed watercolour reflections are picked up by the glass. I know it can be done by a professional in a studio with the proper setup.

A polarizing filter MIGHT help. Just a thought.

How large a picture? You might be able to use a light tent. If not, then a polarizer is about your only option. Just get a linear polarizing filter of a large enough size and hold it in front of your lens. Rotate until the reflections are minimized. You will probably need the camera on a tripod.

Here is a link on a subject called "family of angles"
http://studiography.blogspot.com/201...of-angles.html

A light source(s) placed outside the "family of angles" will not reflect into the lens.
Commonly used for shooting dark-field and light-field (sometimes called bright-field) images of glassware and other very reflective objects.
It will work for imaging paintings behind glass as long as you can control all stray light.

Link might help to get going quickly:

As mentioned a polarize can help, but you said it is not an option for your camera.

There are few cameras that can't accept a polarizing filter of some kind. Even if you can't mount a filter on your camera, you could just hold it up in front of the lens and it will work fine.

See http://en.wikipedia.org/wiki/Polariz...r_(photography)

Thanks Peter, plenty to digest. I'll get on with the reading and hopefully can achieve some better results than hitherto. Another attempt with a tripod manipulating side curtains to minimize reflections has proved good enough to satisfy a request.
