I was going to post this in critique but I really can't compete with the quality over there. In other words I chickened out.
This is my attempt at fairly low budget studio portraiture. There is one strobe to the left and above the camera. It probably should have been higher but the ceiling and the model's height prevented that. The strobe is bounced off of an umbrella. Fill is by white poster board and general leakage from the strobe by the white walls and ceiling. The backdrop is 18% grey seamless paper which I used because it's all I have available. The paper is (unevenly) lit by a pocket SB-30 slave which again is all I have available. The uneveness of the lighting doesn't really bother me although I would have preferred the brightest spot to be up behind her head. For me, lighting the black and white was a huge challenge and I guess I failed to capture a lot of detail in the black but it was the best I could manage.
The camera is an old Coolpix 5000 at F/7.2, ISO 100, and as much towards the telephoto end of the lens as my space would allow.
By the way, the only excuse I can offer for the open shirt is that buttoning that next button produced unsightly gapping.
I'm a beginner at this so I don't know what I don't know. Any suggestions and criticisms are welcome.
