Almost all modern SLRs have a focal plane shutter. A focal plane shutter goes by that name because of its placement. It is placed right in front of the film, or sensor, in the focal plane.

For those who have no clue about photography, you must be wondering why the word ‘shutter bug’ is often used interchangeably with camera.

Most of us believe that f stop and focal length are the only two parameters for judging a lens. For the uninitiated, lens speed is another deciding factor when it comes to lenses. A lens can be termed a fast lens or a slow lens.

If you want to express the speed of a moving object with respect to its surroundings then the best way is to capture motion blur in your photograph. Capturing motion blur requires a lot of proficiency and experience, hence it is an extremely tuff discipline of photography for novice photographers.
