Use a bit longer than normal lens and shoot from ca. 3' to get full frame=full screen; using a 50mm even with macro will tend to give you some bending. Figure about a 1/4 sec. exposure to minimize diagonal banding problems from the screen refresh, and set aperature accordingly. If you need to take a picture of someone USING the screen, as well as have what's ON the screen show up, use a flash w/slave setup to light the scene-and-person, set flash distances/etc. to give proper exposure with the aperature you're using for the screen, and shoot at 1/4 sec in total darkness, letting the flash and slave illuminate the scene for the proper time at your desired aperature, and the screen to "burn through" during the rest of the 1/4 second. Hope this helps; we publish these regularly in an in-house offset magazine and the work out pretty well. Theodore Allan Morris, U.
