My Siamese, Sebastian, is very photogentic. He was sitting on a window sill and everything was distracting him. Especially with the reversing ring on the camera, you have to be right up close and if he moves a little you're out of focus. So what I would do was focus in on him and then scratch the wall. He'd look up to see what that noise was and I snapped the picture.
Even with the soft focus this image works nicely It would be beautiful as a high key portrait with a little Photoshop work but none the less an excellent image,
