This onion had been sitting around for a few days and had dried out a bit. Perfect. I set it up on the floating bench, balanced on an oven mit, and with the camera slightly elevated using the nearest thing I could find. I set the camera to aperture priority, and stopped down a great deal so that the insides of the grooves would be in focus as well as the surface. This also meant that even if the camera wasn't dead straight on to the subject, it would still be in focus. (Otherwise, with macro photography, the depth of field is so narrow that any difference in angle will mean parts go out of focus. Sometimes it's a good thing.)
The camera being balanced on the table let me set off a timer shot and keep my hands completely clear. I try to use ISO 100 where I can to minimise noise, but that only works if the camera is not hand-held.

Lightroom - In curves, I dropped the shadows right down to emphasise the pits on the surface. I also used the blacks and clarity bars for the same reason. I raised the colour temperature of the shot by a small amount to counter the harsh cold light of the kitchen flouro, and give the photo a warmer feel. I also cropped and rotated slightly. I was trying to replicate a version of this that I had taken the day before, but chose the foggy morning photo instead. I didn't get it exactly the same, but it's fairly close, and no-one will ever see the first one, so it doesn't really matter!
