I've always loved this type of close-up, dog-nose shot. They're so cute. Unfortunately, I couldn't get my dog to cooperate; until I got a doggy bone, that is. Then he sat patiently while I took his picture.
This is one of my first tries at black and white, and I must say that, personally, I love it. The color version had all kinds of awful distractions that just aren't present in the black and white version. The only thing I did was color the eyes, which I think works well.
