I recently had the opportunity to play guitar in a production of Grease. It was a bit of a nerve racking experience as I hadn't played guitar in front of people for a while but it turned out well ... I hope. While I was waiting to come on, I shot some photos of the performance. The light level, quality and variance turned out to be a real challenge but it was an great experience and I think some of them turned out quite well.
The photos were taken in a mixture of Av and M mode. Av mode was used at f4.0 and I set the manual settings to ISO 1600, f4.0 and 1/250th. The choice to move from Av to M mode was driven by the fact that I wasn't stopping some of the motion. Initially, I was getting a f4.0, 1/160th reading from the camera. I then decided to pump it up to f4.0 and 1/250th and just deal with the resulting noise in the shadows at ISO 1600. I did use Lightroom to remove the ISO. Overall, I'm quite happy with the result but I would love another chance to get in there and try this again ... especially with a Canon 5D mark III!
