Agree with @amandal. Great shot. Looking at this on the ipad. Have done the whole 'pinchy out' thing with thumb and forefinger. The look and reflection enlarged is perfectly captured.
@motherjane thanks.....wouldn't look too close, its at a ridiculous ISO only way to shoot inside a bus in a dark museum!! Your girl looks a stunner by the way.
@newbank Thank you. She absolutely is. Aged 15 (with attitude) hands like shovels, long graceful fingers, legs up to her neck, perfect natural eyebrows, size 8, polite, thoughtful, funny and a straight A student. Her only downside ..... she hates being photographed!!
