I first visited Ulrich Mueller’s lab at the University of Texas in 2007, where I took this photo in one of his lab colonies of Mycocepurus smithii:

The photo shows a worker on a strand of fungus that grows in ant nests. The fungus eats bits of detritus that the ants gather from around the forest, while the ants eat the fungus. It’s a true agricultural system. Plenty has already been written about these fungus farms, so I won’t bore you with further detail.

Since I was back in Austin a couple weeks ago, I figured I’d have another go at shooting the ants. Have a look.

I used the same lens & an upgraded camera back, but this time I was armed with two more significant weapons: a pair of remote flashes that I could position freely, and seven additional years of experience to guide where I put those flashes. This time I arranged a diffused side light at left, and a diffused back light at the right, with nothing but empty laboratory space behind. The effect, I hope you will agree, gives a bit more zest than my first go.
