I was inspired by one of the macro tutorials in a Kelby Training online tutorial, to shoot a lemon with bubbles.
The set up was easy enough - light tent, with a black background. My 5D II + 90mm Tamron lenses was mounted on a tripod, and I placed a square vase on an upturned bowl (to raise the vase off the bottom of the light tent).
My speedlight, sitting behind the whole set up, was dialed down to 1/64 power and triggered remotely. Then I just experimented with aperture for different effects.
I did a few test shots with the lemon clipped into place to check focus, then added a litre of soda water, which bubbled around the lemon.
Here are the final results (including the set up of the shoot) :)
