Here we go with a negative about 15 years old I shot on the half plate camera below. Waterhouse stops, in frame, no shutter, lens cap off and count the secs. Lens is dated 1904, have they got any sharper?
Can't remember the emulsion but you could still get half plate (6 1/2 x 4 3/4 inch) off the shelf then. looks like my wash and fix is holding up. Anyway the V850 was the test so this is just on the scanner bed @1200 nothing on top straight scan with the Epson scan programme then downsized for web.
I'm off now to look at technical cameras
Apologies for the rotten camera product shot just needed a quick and dirty one for Flickr.
