I think he'd settled on my camera bag when I took this (he spent a lot of time hanging onto my softboxes too - grr). I placed one softbox very close above and behind, and one on the side slightly further away. I dropped a tiny LED torch inside to give me some light to focus by.
The lens was set to 5x, so with the teleconverter this must have been about 7x magnification.
