This wedding was at a golf club and we were just finishing the bridal portraits when this idea came to me.  I had the bride lay back on here gown and I zoomed my flash in to make a small circle of light.  This is a very cool effect and every photographer should learn how to do it.  I then shot it at a fast shutter speed to get the darkening at the bottom.  I could easily take the blue out of the bottom but I like this effect.
