Jon,

Once the Kreene arrives on Monday I will remove the glass and have a  
similar setup to you. The Mylar was just a temporary replacement.  
I've removed the glass once before and had it crack on me, so I know  
what you mean by intimidating!

I use Dan Welson's screen which is surprisingly fine compared to  
Elizabeth Dove's. I'm curious to know how fine it is compared to  
yours. I should send you a piece to compare the two. I have a 5K lamp  
used in conjunction with an integrator. Before I pulled the frame  
apart last week and changed the foam pad and started using the Mylar,  
my exposures were very close to yours. Since the changes however, my  
exposures have increased, about +20% which isn't a problem. I'm  
waiting for the Kreene to arrive before I make any more tests though.  
I'll let you know more next week!

Keith.
