I still can't figure out colour space, that's for sure. I know it's complex, and I'll keep trying. This picture is a great example of trying to use Hue/Saturation (upped the sat on blues/cyan, downed green/yellow) to recreate the image I got out of the LCD viewfinder. I've noticed that working with Hue/Sat before downsizing to a web resolution comes with grainy surprises. All that speckling in the ice at the top of the shot was not as noticeable when there were 2560 pixels to work with... :-) I'll keep trying. I'd love to know if this image works or not, for any reason - I find it a bit hard to look at, but I like the blues. Thanks!
