I was officially digitally imaging the concert for the Sounding Board. The venue was very dark with no lighting at the stage, only limited ambient room lighting. Still, I was able to get a few reasonable images. I, personally, prefer to only use the available ambient light, no flash. I also prefer to image from behind the audience so as not to distract the performers and the audience. I usually use a moderate length fast telephoto lens. In order to get anything viewable under these conditions, I had to push the sensitivity (ISO) to 1600. My first image of the concert posted to my flickr gallery is viewable here. Please bear in mind, viewing in the Original Size will clearly show all the imperfections, including camera noise (graininess) and blurring from subject movement. The text with the image describes how I took the image.
