I have found that Fujichrome 50 results in more accurate colors in
photographing my IBM VGA screen.  1/4 second is the minimum shutter speed to
eliminate the retrace problem, but I prefer to use 1/2 to 1 second.  Using a
100-200mm lens and tripod in a dark room, I generally shoot around 1/2 second
@ F11 or 1 second @ F16.  However, I recommend that all shots be bracketed by
one stop each way.  The exact exposure will vary with the subject on the
screen.
