I had a couple of attempts at this. My first image of two aubergines lacked interest. I spent some time arranging the lighting and choosing the camera position to improve the highlights from the skin. The lighting setup is shown below:
5554: 1/125s f11 35mm standard f1.8 lens.
After some more thought, I decided to use slices of fruit to show curves. The lighting is shown below: Large softbox on full power, small on ½ power.
5561: 1/125s f10 35mm standard lens.
