1. Shoot from the hip
Literally. Don’t bring the camera or phone to your eye, that way your subject won’t see you shooting.
2. Stay ready
If you’re using a camera, keep it covered with no lens cap, that way you can move quickly.
3. Keep looking
Look in unusual places for subjects and for unusual viewpoints.
4. Be patient
Stop, wait and look. Sometimes you can see a great moment coming.
5. Be sneaky
Use shop windows to check the scene in reflection.
