The "F" Word

The "F" word sprang to mind when I saw this on the LCD. No, not the ones of frustration when I realised I'd been shooting on a tripod with the image stabilisation still on! No, not fern, not frond, not furl but Fibonacci.

As it turned out I had taken the shot with the centre of the spiral spot on a horizontal and vertical 3rds line! I get quite excited about that sort of mathematical thing!

I'm easily pleased!
