Hi Robert,
I have to confess that for the moment I haven't had the chance to photograph burlesque dancers! From what I understand they can move about the stage rather fast. For that reason, the opportunity to find one model sitting in the one place for a few minutes at a time must be rather enjoyable. That, and the fact the someone has gone to the trouble of adding some light to subject, really helps. Overall I like the image and the lighting, but there's one thing I find a little annoying; it's the burnt-out highlights of the skin, particularly on the model’s arms, chest, knee and the side of her face.
Part of the problem here is likely to be the control of your exposure. One old adage from the slide film days was always to “expose for the highlights”, which is to say, make sure that you don't over expose them to the point that they look white. With digital files the same notion holds true; you never want to overexpose the image. As a heads-up, most cameras offer a highlight warning in the playback mode. When this option is selected, parts of the picture will flash in playback to show you which parts of the picture are blown out, thereby giving you the chance to make adjust the exposure. If you're working in one of the auto-exposure modes then you can use the “exposure compensation” control to dial back the exposure one or two stops. If you're working in manual mode then all you need you need to do is use a slightly faster shutter speed.
Even though exposing for the highlights will also make the shadows darker, you actually have more chance of recovering detail from the shadows than you do of recovering detail from blown-out highlights. Ideally, if you get the chance I would also be making photographs in RAW mode. RAW is very much like JPEG mode, in that you are better off under-exposing than over-exposing the file, but RAW file is exceptionally more forgiving.
Aside from that, this is a good effort.
Cheers, Anthony
