Here are two photographs depicting a bevy of young caterpillars skeletonizing a parsley leaf:
In the first, light is provided by two diffused strobes from above. In the second, the diffuser is removed, eliminating the even reflection off the surface of the leaf, and one of the strobes is shifted to bounce off a plain surface behind the leaf, effectively back-lighting the shot.
It seems that half my posts on photography concern lighting, but there’s a reason for that. Photography is all about capturing light, and the best photographers exercise obsessive control over illumination. The second shot conveys the effect of skeletonization much more strongly, in my opinion.
Incidentally, do any of you recognize the caterpillars? I have a terrible time identifying young lepidopterans.
