Marvin digs his modeling responsibilities. Often, all I ask of him is that he lay down in a cozy spot while I fiddle around with my camera and then he gets a treat. And repeat. It's a sweet job for a happy dog. And, to be honest, he's far more cooperative about my fiddling than his brother right now. I'll be using him as I experiment with new techniques this summer.
