Just as I wasn't really sure how to produce a silhouette with my camera I was really in the dark when it came to long exposure. Joe explained it to me then showed me what settings to change to get the best results. I knew I needed a moving target and figured who better then Jack! He normally blurs half the shots I take of him without any special settings anyway!
I think this one is my favorite. That blueish grey smokey looking thing is actually Jack!
We kept asking him to run back and forth across the living room, it was hilarious.
