I have to shoot paintings and frames for the online catalog for an art gallery. I'll shoot with my Canon 5D mark II and the Canon EF 50mm F1.8 II and 17-40 L lenses. The gallery is basically a store and paintings and frames are stored in a relatively small area. I'll be shooting horizontal and vertical depending on the painting - what is a good light set up? How do I minimize reflection on the glass fronts of the paintings (for ones that are framed in glass)? What is a good ISO in these conditions (there will be store lighting, mostly bright white lights and some tungsten). What f stop should I be looking at? Anyone who has done this previously, are there any creative techniques or angles? To me, it appears these will have to be front-on shots but there could be other possibilities. Thanks in advance.
