I love shots which show the passion for photography. Taking pictures is the art of seeing which I admire. Being far from mastering it, I can only try to improve.
I try to put the pictures as they are to flickr, except for resizing them. Sometimes I clip the shot to improve the image. A few times I slightly Improve colors or contrast. Rarely I resharpen the image. The goal is to get the shot right and not to rely on Photoshop (or actually Gimp). But that's not always possible.
