Park Avenue in Arches N.P.

I was inspired by a "Platinum" image that Tom Meyer did of a magnolia--you can check it out here:http://www.photo.net/photodb/photo.tcl?photo_id=1619736(You'll have to scroll down the page to find it...)Anyway, this is a color slide, converted in PS 7--I generally use Channel Mixers/Monochrome from an 8Bit file, but this time, I started with a 16Bit scan, adjusted the Color Balances until it was way too RED, then I coverted to 8Bit. Went to B&W with Channel Mixer/Monochrome (80 Red, 20 Green), and then adjusted Levels separately over the sky, the tree trunk, and the entire "landscape" in the bottom half. Flatten, convert to Greyscale, then to Tritone. I pretty much used trial and error to come up with a pleasing "sepia" tone, mixing various combinations of three colors.
