I have the exciting opportunity to catalog and photograph a small museum collection. The items will mostly be prints, paintings and possibly a few photographs and sculptures. Some of the works will be framed and behind glass. I know that a whole career can be devoted to doing this kind of thing right, but I'm looking for some general tips & information that will help me get the best results. I'll need to bring a small lighting setup, and I'm wondering what else. The typical setup seems to be two lights at a specific angle to the print, to avoid glare. I'm slightly curious about "cross polarizing", but unfortunately I don't have polarizing filters large enough for lights. Any insight will be helpful. Thanks!
