So here's image #1 - well, it's not strictly #1, I've taken thousands of images, but this is the first genuine attempt to do something interesting - I've attempted to add rimlighting to this cactus. The results are not so good, with only one flash, I had to reflect the light from the back down onto the front, but at least you can see the flesh in this one - the first few were black.

Valuable lesson learned - another flash would be peachy.
