Colin -
Just for grins I tried exposing under an enlarger for a day and a half.
Needless to say, nothing happened. Exposing by sunlight is a great way to
start, but if you want to get serious about it then you'll want to build a UV
exposure unit. This will give you the repeatability you cannot find with
exposure by the sun (your times will vary with the time of year, time of day,
clouds in the sky, and on and on).
Cheers -
