I tried an acid-etched glass to replace my standard 4x5. While I was impressed with the clear screen and high contrast, I had a harder time focusing a wide-angle lens. This was due to an increased 'hot-spot'. So it became very hard to compose with my 90mm f8 super angulon.
I was thinking about trying a satin-snow glass. So I would like to know if anyone has opinions about the satin-snow product in context of the hot-spot. Thanks.
