Hold the camera tightly against your face. Take a breath, hold it, and gently squeeze the shutter release. Chances are that you'll make a picture free of camera movement. Golfers practice their swing. Target shooters practice squeezing the trigger.
Photographers can practice their handling techniques.
With most of these, you view your subject through a viewfinder that is separate from the camera lens. These relatively small cameras have become increasingly popular, and they commonly include features such as automatic film advance and rewind, automatic exposure, and automatic focus. A hinged mirror reflects the image through a pentaprism in the viewfinder to your eye. When you take a picture, the mirror flips up to let light reach the film and then returns to its original position. One of the major reasons for this is that it's so easy to use interchangeable lenses with them.
