The overwhelming majority of snapshots show people smiling at, gawking, and clowning for, the camera. And there's certainly a place for pictures like that. But what pictures do best is capture people being active, involved with work or play. That's what you get when you take candid photographs.
Candid photos are often the best and funniest.
Instead, photograph them as they are even if the baby is wearing most of his dinner, or Buffy's hair is a mess. Instead of taking 30 pictures of the family standing in front of 30 different tourist attractions, go for the action. Shoot the kids swimming in the surf. Catch your spouse hugging Mickey Mouse at Disney World. You can take great candids anytime.
