Rachel, Archer,
Thanks for your comments and thoughts about my picture. The lighting setup using 2 lights only seems to be working pretty well according to all the comments I have heard in the meantime. BTW the phrase "chiaroscuro" sounds so much better than "paining with light" since it reminds me on the soft and silky light in the morning and evening around the Mediterranean.
Portraits without showings the full head sometimes tend to split viewers in controvers positions. One part likes it, the other is not so happy with it. I have got some other shots in portrait presentation with her full head visible. I definitely agree these shots work in a very different way. Since I wanted to get more input on the idea of a picture composition with the model's face placed very high I selected this specific picture. Maybe lifting up my camera position by 10-20 centimeter still keeping the same picture composition might work fine. Re-compositioning the picture's format in post production to a square reducing the clear space to her left seems to work pretty good as well.
Asher, after playing around with my picture for a while your remark about sharpening is adressing the right point! In the current picture sharpening is too aggressive for presentation on screen. Using a more moderate parameter set definitely works better since it removes some of the harshness from her hair. On the other side this particular styling of my model's hair is a little bit unusual for her. Bearing this in mind we are currently discussing on how to highlight this detail the best way.
Regards,
Bernhard
