I was quite sure that the strings on a Tennis racquet could be used to produce bokeh if lit from the correct angle. I decided to test this out yesterday and produced a couple of photographs which doubled up as this week's entry for my project. The main problem which I had to contend with was working out an angle which produced bokeh as well as a half decent composition for the photograph itself.

Lighting Setup - Ace
This again was a two light setup.
The main light was a bare Canon 430 EX II fired at 1/64th from camera left. This light was used to light the closer edge of the racquet. I placed a white foam-core board at a slight angle under the racquet to bounce the light from the 430 EX II back onto the under side of the racquet and create some separation on the black bottom edge. The effect is subtle and can be seen on the bottom edge of the racquet on the right hand side of the "Wilson" sticker. If I hadn't placed the white foam-core board under the racquet, this section would have been black and would have merged into the background.
The bokeh was created by a Canon 580 EX II fired at 1/128th from in front of the camera and slightly to the left. This flash had a CTB gel on it. The light from this flash also created the highlights on the further edge of the racquet.
I used a black foam-core board as the background.
