Don’t use flash! Flash is the enemy—it creates harsh shadows and unseemly glares, which can result in an improperly exposed photo.

The first image was taken with the flash on. The edges of the photo are dark, and there is a harsh shadow behind the hand.

The second image was taken without the flash. There are no rigid shadows, and the background remains well-lit without falling into the shadows at the edges.

If you find yourself needing to use the flash, it's a good sign that you need to add more lighting to your setup.
