Spend time studying the species and habitat of what you’re shooting… especially kids cos’ they move around a lot!
Try to visualize the shot or type of shot you want to get. Then observe your prey carefully within it’s natural environment and when the time is right… fire!
If you miss, pretend to your quarry that you got the shot you wanted and lull them back into a false sense of security. Begin the stalking again.
Whenever Possible Shoot Using a Tripod or Alternately BE the Tripod
No this isn’t a lesson in method acting. Obviously there are many situations where using a tripod is simply impractical but…
It is a good idea to always think of stabilizing the camera at least in some way if possible. The greater the zoom you are dealing with or the greater the compensation you are making for low light the greater the possibility that camera shake will enter in.
If you can’t use a tripod or monopod then try to make yourself into on. Lean against a wall or even lock your elbows against the side of your body.
