I was looking at the archives at the Alt-Photo-Process-List and came across this thread: http://duke.usask.ca/~holtsg/photo/current/0257.htm. So I jumped up and grabbed a can of Krylon Crystal Clear Acrylic Coating 1303 and a throw away palladium print and went outside to spray it. Wow. The print I used was overprinted and outside the negative area was badly solarized but just one coat and the solarization was gone. Brown became black. The Dmax also improved, not a huge jump but definitely noticeable. There were a couple of other new discoveries for me also. The shadow areas that were blocked up suddenly had separation and new life. So I started grabbing another overprinted print and before I coated it I put it up to a lamp to look at it transmission style. It had all kinds of great seperation in the shadows that just blocked up in reflected light. I sprayed it and it came to life. Anybody else do this?
