-
- I have had good results with Kodak Ektachrome 100 daylight slide film.
- The hard part usually is
- framing the screen (not getting the monitor cabinet into the picture).
- Remember that the SLR's viewfinder "overscans", that is, you get a little
- more on the film than you see through the viewfinder, and you may not be
- able to zoom in enough to avoid getting some extra stuff on the edges of
- the picture. If it still shows up on the slide you can cover it with
- tape.
-
- Turn out the lights and perhaps cover the monitor cabinet with black paper
- or tape. Make sure that the camera's lens axis is perpendicular to the
- surface of the center of the screen; distortion is more obvious when you
- see it on film. Take relatively long exposures (1/2 to 1 second) to
- minimize bright bands caused by the screen refreshing. If you have
- automatic exposure control, let it do its thing; don't second-guess it.
- Allow yourself enough time to re-take the photos if they don't turn out.
- Good luck! -- Mike
