I need some advice on shooting slide film from someone who is knowledgeable on exposure and slide film characteristics. A friend of mine, a very fine artist, is entering a piece of work in a local contest. The contest rules state that all entries (prior to framing) must be photographed with 35mm slide film and one, and only one, slide is to be submitted for review. Only "x" number of entries will be selected for final entry into the contest.

He has asked me to photograph his entry and I need some advice on proper exposure and suggestions on the most appropriate, literal but flattering lighting.
