The sun was hitting this curl in a Philodendron leaf, I did not add any light to it. The f3.2 setting made the grass in the background green and brown blurs and I deliberately shot with a wide aperture to catch just the edge of the curl in focus.

Post processing: Increased the recovery slider, blacks, clarity and vibrance in ACR. In CS3, duplicated the background layer in Multiply at 60% opacity, selectively sharpened the curl only, added a clipping mask frame by Jessica Sprague which also included the texture.
