Out of almost 300 shots my favorite is the one where she's not posing for me at all. This is my first attempt at shooting portraits. Available light only. Please offer suggestions if you feel there is anything I could have done better.
Unlike the previous reviewer I like the expression - it's not a simple 'I don't want to be photographed' look. I can't quite say what it says to me but if I could I suppose I wouldn't like it as much! I do however find it a bit muddy - In the attached version I've just scooted the white point on over a little bit. I think it would be markedly more attractive if you play around some more with the levels or curves or whatever your poisin is.
In the spirit of "Be brutal. Be honest." I have to express my curiosity at the fact that this is your favourite of the shoot. She looks like "Oh my god I'm being photographed, what am I going to do". Not the most flattering expression for a portrait :-) On another note, 300 shots sounds to me like quite a lot for the first photoshoot session. Perhaps slow down a little? But I can understand the excitement of using a new camera :-)
