Greetings.

A question for those of you who have taken pictures of your VGA screens.
What exposure time is most appropriate?  I know it needs to be long enough
to avoid the screen retrace, but what is optimal?

I recently took slides of some color diagrams done with the paint program
included in Windows 3.  I figured 1/8 second should be adequate, yet the 
slides demonstrated broad diagonal swaths of darker colors that appear to
be retrace related.  Otherwise, the results were quite nice using the
Zenith FTM monitor.

Thanks for the help.  I'd rather not have to use another roll of film
experimenting with various exposure times!
