Length of sunlight exposure of photosensitive boards

2011-05-07 by James English

Hello, I'm new to this group, though not new to electronics.  Does anyone out there have experience with exposing a photosensitive board through a negative to sunlight?  A man at Injectorall told me that about six minutes at noon on a bright sunny day but that doesn't seem to work.
