I've been reading about histograms and found this very interesting:
http://schewephoto.com/ETTR/index.html

ETTR - Expose to the Right for best signal to noise ratio.  I've tried it
with several experiments and it's amazing how much slight overexposure can
help with noise in the shadows.  There are other sites trying to disprove
ETTR but I've found it works for me.  Looks like that's what you've done
with this one, too.
