You can’t tell from the thumbnail, but this photo of my eye is actually divided up into four quandrants and a different filter was applied to each area.
Speaking of art (we were speaking of art, weren’t we? Or maybe I was just thinking of it – oh, well, no matter), I found this really cool online artist community yesterday called Wet Canvas. I haven’t had a chance to wander around in it much yet, but it has over 7000 members and a huge number of forums from watercolors to art shows to digital to photography to selling art on the internet.
