This is Katie. Justin and I have three dogs (we had four until we lost Raisin back in August 2013). I find the dogs hard to photograph in "portrait style." Yesterday I discovered that being sneaky and not engaging them or distracting them from their lounging, I was able to get very powerful photos. The black and white accentuated their contemplativeness.
Update: In May 2015, we once again became a four dog family. Bella Luna was rescued as a puppy from the local pound.
