Photographic models.

I was out in our son's garden doing my homework for " A Year With My Camera". The task was to check the histogram before taking a photograph and use exposure compensation to make it do what seemed right. These 2 seemed willing to pose, This was taken with an exposure compensation of + 2/3 of a stop. Two weeks ago I didn't have a  clue what the histogram showed, far less how to use it to get the exposure right.
