I have to confess that in some ways this shot is a bit of an accident, at least as it's presented here. I had intended that this should be a 3x2 format shot, two-thirds of the shot being taken up by the yellow shutter, but I totally messed up the depth of field which left the leftmost third of the shot far too blurred. Anyway, having decided to go for a square crop I'm much happier with it.

Oh, and I'm puttting this up a bit early as I'm going to chill out this evening: crap TV, chinese food, and a couple of bottles of wine :-)
