Here is a shot I took this time last year in WV. Shot with 50 speed Velvia, F5, 28-70/2.8 on a Gitzo 1325 with AS ballhead. Slow shutter speed - probably a second at somewhere around f14 or so.
Scanned with a Nikon 4000 scanner and lightly edited in PS. Surprisingly little color fix; just there at the rght place at the right time. Velvia doesn't need to much enhancement. I did clone the upper left corner and lower right corner to get rid of some small areas of distracting blue sky and blue water in the respective corners.
