When (not) To Use Flash

What is photography's greatest scourge? Cellphone cameras? MySpace self-portraiture? Neither even comes close to the insidious, creeping threat that is your camera's built-in flash. Here's when and how you should—and more importantly, shouldn't—use a flash.

Avid photographers, you already know the score, and this isn't a guide for you. Nor is it for the dude with the brand-new 5D Mk II with an external flash gun, or the weekend strobist. This is a reference to be passed around as a public service; a quick guide for the aquarium-flashing, face-flushing, baby-blinding friends and family you all know and tolerate love.
When You Shouldn't:

At Large Events
Every time I go to a nighttime sporting event or concert, I see hundreds of starry flickers coming from the stands. When I see them, I die a little inside. For your average point-and-shoot, the effective range of your built-in flash is about 15 feet. You might stretch this to 20 feet if you jack up your camera's ISO settings to 800 (or God forbid 1600), but under no circumstances will your camera's flash reach down to the field or stage.
