You may notice there's a little more light in these shots. Why? Well I just discovered that the ring flash and the 580EXII speedlite have wireless connectivity BUILT IN!!! I had no idea. I saw there was some sort of wireless transmitter you can buy and thought you needed this thing to wirelessly link flashes (you don't, and there's actually a Camera Labs review on this kit!).
