Concepts in Photography
Standing photography
Compose your shot, stand up straight with your feet shoulder-length 
apart, and keep your elbows pointed down.
Shooting postures
A correct posture for stabilizing the camera is necessary for taking a good 
photo. Even if you hold a camera correctly, the wrong posture can cause 
the camera to shake. Stand up straight and remain still to maintain a 
steady base for your camera. When shooting with a slow shutter speed, 
hold your breath to minimize body movement.
Holding the camera
Hold the camera with your right hand and place your right index finger on 
the shutter button. Place your left hand under the lens for support.
