I have developed a new material and its coating process, "Super Bright", to brighten up the existing ground glass, up to almost 2 f stops. I will email to anyone interested in it actual photos the side by side ground glasses taped together, one S. B. treated and other not, onto which an image is projected. It clearly shows a dramatic difference in the brightness of the two ground glasses. I tried the S.B. coating on four different ground glasses from Graphic, Polaroid MP-3, Linhof, 5x7 B.J. Satin Snow, and Sinar. You will see the images of the all those treated and treated g.g.

p.s: Please send me your e-mail address, I will reply with attached photos.
