Re: [APML] First results with GEG

Darin,
Good job.  It doesn't take much to burn the trapezium out does it..?
You might try masking it next time. See Jerry Lodriguss' Site for the 
article.
Its really quite simple and straightforward.  If you do expose longer next 
time, you'll definitely
need to use a mask.  Of course, you may already know this technique.

Grant
