wow this seems to people's favorite photograph of mine. Unexpected!
Post-processing: Crop, convert to b/w, then to duotone. After that, 2 layers at 45%ish transparency, overlay blending mode, one for white paint brush to lighten up the hand and frog, one for black to darken the borders. Then some erasing of the brush to get the desired effect. Then levels/curves work, dodging and burning on the points of interest, and some selective blurring of the distant parts of the hand.
just came to pik a fav pik and saw this ..
love your photography and this is another brilliant one .. love the details and the different between his little feet and the big hands/fingers ... excellent process .. :)
