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.

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…
