When you are photographing someone every moment can count. I usually try to focus on the eyes. When I first saw this photograph of Nicola I was quite taken by it which is pretty awesome considering it was taken by me. (That line just came to me as I was typing it). We were sitting in a crowded coffee shop (Yes Starbucks) and I was going click, clickclickclick, click with the camera. Just for a moment she found it too funny and had to look away.... I could have put the camera down but pressed the shutter and caught this moment.
Nicola's moment of mirth was captured with the 50mm(of course) 1/40th sec f2 iso 200
