Focus and take your pictures

Once you’ve composed your picture and established the correct exposure, make your subject sharp by setting the focus, either automatically (autofocus) or manually; most cameras offering autofocus have a switch that allows you to choose either manual or autofocus. In most cameras, to use autofocus you push the shutter button halfway down; there is often an indicator such as a green dot in the camera’s viewfinder that lights up when the subject is in focus. For manual focus, you turn a focusing ring on the barrel of your lens until you see the subject become sharp as you look through the camera’s viewfinder. Once your picture is composed, the exposure set, and the subject focused,

press down on the shutter button to take your picture. Be very careful to hold the camera steady while you press the button; if your camera moves during the exposure, you may get a blurry image.
