Storm Surge, photo by Harold Davis. View this image larger.
This photo composite comes from LAB inversions of a channel of Poppy Medley, LAB inversion of a channel of Breaking Wave that was a by-product of the black and white conversion, and Sunset.
I often file and save channels that look interesting to me as I do my LAB channel operations. If these are not immediately useful, I find that they can be great fun to play with later on.
