My loyal friend, Trixie, is in a belly dancing club. I didn't even know there was such a thing. On occasion, they have what they call a Hafla, which is where they put on a show. I told Trixie I could come and take some pics, and she mentioned it to the instructor, so I got pulled into taking pics for the whole thing. A new experience, never really tried an indoor type of thing.
The best I could come up with was to detach the flash via a 2ft shoe cord, and mount that on a tripod. I took the pics from the side. It wasn't the most high-tech thing in the world, but at least getting a couple feet between the lens and the flash successfully eliminated any potential red-eye. I had taken a few shots at one of these things before with the flash mounted on the camera, and from a distance of 20ft or so got red-eye in almost half the pics. I'm now a big fan of the flash cord. I did get a strong shadow on the background, though.
