The most amazing thing! I just gained about two stops of brighter image on my old ground glass BY ACCIDENT. I still don't believe it but here's what happened: I'm finishing up my home made 5"x12" panorama ULF and I'm restaining the body and the new add-on parts. I'm using regular ole Minwax Natural Wood Finish and accidently brushed a little on the ground glass. A spot about the size of a quarter. Just enough to be very annoying and pretty much in the central part of the glass. Well the stain acted just like water and made a clear glass spot, expept it dried almost instantly and wouldn't wipe off. Damn to hell! I'm going to have to grind out that spot for sure if some thinner of some type doesn't remove it.
So the camera gets done, I hang a little G-Claron 355 on the front, insert the ground glass carrier, and focus in for the first time using my newly installed bellows attachment. Wow. Experiance the THRILL. Dissect the TACTICS. Whoops. Sorry, thats Dog Fighters on TV. I just experianced the thrill.
But then I looked at the big bright "stained" spot. IT SHOWED THE SAME FINE DETAIL IMAGE as the rest of the ground glass, but at least TWO stops brighter.
If you don't believe it, try it. Has anyone else discovered this, or does everyone already know about it and it's just one of those things I've managed to miss for all these years?
