· Shoot at the lens’s widest aperture (F/2.8 if possible).
· Maintain a shutter speed of about 1/125 to avoid motion blur of your subject. Use a higher shutter speed if you do not have image stabilization (addressed in the next bullet).
· Turn on your camera or lens’s image stabilization to avoid your hand’s shake in the photo.
· Be ready to crank up that ISO to 800 or more (1600-3200 ISO). Stages are often quite dim and require a fast shutter speed to prevent blurry photos. Remember, a slightly noisy photo beats a shaky or out of focus image any day! You can always remove noise to some degree, but can’t fix motion blur or out of focus shots.
· Unless you can diffuse or bounce your flash, I would avoid using it. It is also distracting to other audience members and the performers. If you want to use a flash, make sure it is ok to do so beforehand.
· If your camera has a quiet mode, now would be a good time to enable it. This usually dampens the shutter mechanism and flips down the mirror when you press the shutter down and flips it back up when you release the button.
