Lasius claviger at f/3.5
Lasius claviger at f/13
I wouldn't say that either image is better. The first is dreamier, more abstract, more interpretive. The second is crisp and illustrative. Quite a difference for a small tweaking of camera settings!
Most of my insect photography falls in the small-aperture realm of the second image, but on reflection I probably ought to play around more with images like the first one.

What's going on?
Most lenses contain a diaphragm that can constrict from full open down to a little hole, controlling the amount of light that travels through the lens on its way to the film or sensor. The size of the hole is called the…

Odontomachus meinerti trap-jaw ant, Argentina
One perk of being at a research university is the opportunity to shoot the various study organisms on campus. These subjects are interesting- they have to be, or they wouldn't be studied- and when the research goes public I get the chance to disseminate my photographs with the science media outlets that cover the story.
Among my favorite campus animals is the Odontomachus trap-jaw ant, one of the focal taxa in Andy Suarez's lab. The researchers are looking at the biomechanics of the jaw, one of the fastest recorded appendages among all…
