As a writer, sometimes I'm required to photograph a photo, painting, drawing, etc. for print, or as part of my research. This happens generally when the individual I'm interviewing doesn't have the image on a computer, and won't allow me to take it to my office to scan. Sometimes they say, "You can just take a picture of this picture, can't you?"

I can, and I have, but the results haven't been spectacular. What are the best ways to photograph existing photos or artwork (paintings, etc.), considering lighting (natural?), angle of the camera (standing on a loft / ladder with camera in hand looking down on painting?), etc. What is the best way to shoot the photo straight on, without that funny slant that makes it look like you took a picture of a picture?

I encourage any and all advice on what to do - and what not to do.
Thanks!
