Flash Tips

Turn on room lights and have the subject face the lights to minimize red eyes in pictures.

Stand at an angle to shiny surfaces like windows or mirrors to avoid flash reflection and bright spots in your pictures.

Keep your fingers and other objects away from the picture-taking lens, flash, and meter-cell window to avoid dark or light pictures.
