I've been asked by a family friend to help record and catalogue his paintings and artwork, and while most of it is large canvases and un-framed drawings, he has pointed out quite a few which are framed/mounted and behind glass. These works are decades old and removing them from behind the glass won't be practical. Does anyone have any advice for shooting these? For the normal canvas and un-mounted pieces I've got access some Gemini flashes and soft boxes so I don't foresee any problems there, but dealing with the framed pieces is giving me worry. What I'm initially thinking of is grabbing a large piece of black cloth to cover the floor and tripod, angling the piece down slightly (or at least shoot it from higher up) and hoping for the best. I'm going to try some tests at my house over the next few days but I'd appreciate any input!
