Hi Bjorn. Nice picture you have here. I like the composition with the girl filling the frame, but my favourite part is the sunlight on her hair.
I wish the catchlights were bigger; it's just a matter of personal taste, but these small pinpricks one so often gets with flash just fail to deliver for me. They're still much better than having no catchlights at all, though. Short of carrying around a window-sized softbox, I wonder if attaching a big white card to the flash head would make them larger. Have you done any experiments in this respect?
There's something strange here that I don't understand: when I look at her face, it seems a little soft, but when I look at the texture on sleeves of her sweater which is in the same plane as her face, it's sharp. Could there be some kind of optical trick at play here, or am I just seeing wrong?
