So you brought your point-and-shoot camera to the concert?
This is a shot from the front row of the lower box, level to the stage from around 100 feet away. DSLRS were prohibited so I used a point-and-shoot camera (Leica Digilux I) with manual controls to force the camera to shoot at lowest f/number (f/2.3) at a fast enough shutter speed (1/64s) to avoid blur. I set ISO at 200 to minimize noise. My mindset was to capture the bright strobe lights and hope that would be enough to light the artist. I avoided zooming in to the max and opted for a more normal focal length to get the best optical quality the lens offered. Although I got a decent shot, being not close enough remains a problem. Maybe a bridge will do better next time.
