Photography is all about light. Good light can make for great photos with little effort as long as you know the basics of composition and your way around the appropriate settings on your camera Throw in bad light and getting good images from the same camera gets a little trickier. Now you might need to know how to use flash lighting to get the same result. But when using flash isn't an option and you are in a dark environment where the subject is fast moving you better know your way around the camera and have at least one low light lens to get anything useable. To get the shots that will give the viewer a sense of the action some educated guessing of where the action might take place and the timing of it, and a little luck helps.
On Thursday when I was getting ready to shoot the show at the downtown theater that my wife is lead singer for I was excited for the opportunity but apprehensive as to what the final results might turn out like. As a photographer I'm used to shooting in daylight, I don't do a lot of night shots, even less with fast moving action. Normally when I am doing so its on the basis its for my wife's own personal facebook and it doesn't matter much. For this event though there was no other official photographer so the stakes were higher. I wasn't too concerned about getting shots of the band. The low light lens I had at my disposal would do a reasonable job at that.
