I like the tones a LOT! Can you tell us how u achieved the effect in PS? Is it a blend of 2 pictures? If so, what kinda blending technique are you using?
@seemoo: I used the original shot of the tree, duplicated it with layers and turned the sky sepia. Then I used two texture shots (one of little stones and one of wood) that integrated into the shots by using layers. I guess you have to expermient a bit to find the right blending mode for each individual shot, but I use mostly "Darken" an set the opacity pretty low (mostly below 10). With layer masks i take the effect back on some places where it is "too much".
I hope this could help you
@Phototron: I guess I'll have to get back there someday to get the sequel ;-)
