My young friend happens to have the thickest eyebrows I have seen on a young guy. Even though he made very repulsive face on my request to take a photo of his eyes, I did not give up and managed to take about 10 photos of his eyes despite the dim light.
About the editing: I finally learned to divide original colours along a gradient map, on which I had black and white on edges and brownish color between them. Maybe I have been playing with the gradient map before but this time I actually figured out what was going on. This way I could retain the black in the eyebrows instead of having all the colors toned to sepia as would have happened on Picasa.
