rock (in black and white)

A friend recently loaned me his Canon Rebel XTI. I haven't a clue what I'm doing with a real camera, but I'm having fun playing. ; ) Prepare for an onslaught of cat photos; they are my only models. =^..^=

This is Rock, my grey tabby, hunting a light reflected by the lens.
