Canon 40D, Tokina 100mm f2.8 macro 1/160, f18, ISO200. Only the Canon 580 EX Mk2 flash mounted on the camera was used. This shot was taken yesterday using the same camera and lenses. 1/100, f14, ISO100. For this shot I place a Sigma 500DG Super flash and set that as slave at -1 FEC and place that in bounce position with a bounce reflector at the flash head, and place that about 8 inches behind the leaf. The front flash which is the Canon 580 EX Mk2 is also set in bounce position with a reflector, set as master, is camera mounted. Richard

The first image of the pupae has more clarity, colour and definition, the bored image I love the effect of the leaf, but the clarity and definition of the pupae is lost. Is there not away using the slave to compensate for this loss? As an effect on the leaf and a different way of taking pics its great, I think though it might be a distraction if you were trying to encompass the pupae as well (just thinking out loud here so don't get confused in what I am saying).

The second, the butterfly inside is nearly fully formed and the pupae has now become translucent, so the general view is it appeared grey and not uniform. What this experiment is about is to show the focus of attention can dramatically switch with different lighting effects. When the butterfly is about to eclosed the pupae shell will become almost transparent. Richard
