I made my first attempts at unsharp masking this weekend and I must say it was probably the single most depressing and frustrating darkroom attempt to date. Are there any good web links out there giving tips on this technique. 90% of my google search turned up the usual links related to Photoshop unsharp mask (sign of the times.) My main trouble is judging exposure, development and contrast of the actual mask. I'm also assembling the thing with a loupe and lightbox which isn't that easy no matter what Barry Thornton says in his book. Also, does everyone use a glass negative carrier with unsharp mask? I don't have one so I was trying to improvise using Anti-Newton glass from slide mounts and its not working out very well. I'm at a stage where I want the sharpest looking prints possible, but this whole ordeal is making me rethink my goals!
