Gerbera Daisy

Today we went to the home improvement store to pick up some paint for the deck and some flowers to replace the ones that Bert and Ernie ate. These gerbera daisies were just put out on the shelf and were very pretty. 
I experimented with different flash strengths using the dial on the flash trigger. The lower numbers had more powerful light than the higher numbers. It is very fun to be able to control the light so easily, and the invisible black background has been great for learning the flash. I would like to get a second speed light, but don't know what to get.
