['chelle, is the Dimage XT a digital?] If you are allowed to use flash in the studio, that may be the easiest. I'm not really familiar with your particular camera, so I do not know all the options you may have. The little tiny flashes built into the top of cameras generally give harsh results. Better if it is detachable from the camera. [If it is digital] the ISO speed setting perhaps can be increased for better performance in low light. [With film cameras, can just get faster film.] A tripod will help you to steady yourself, and should work wonders for overall bluring. Camera movement is the #1 killer of good shots. In low light situations you are often forced to use very slow shutter speeds, like 1/30 to 1/15th second. It is generally impossible to hold this steady. If you do not have a tripod, at least try to brace the camera on something steady, like a table top or door frame. It will not keep the moving subjects from bluring, but at least the surroundings will be sharp. [Sometimes having the musicians blur makes an interesting effect.]
