The 4 basic operations of photography are aperture, shutter speed, exposure, and focus.

Aperture (f-stop) refers to the size of the hole that lets light in.  Note that a smaller f-stop number means a bigger hole!  The smaller the aperture, the clearer the images.

Shutter Speed is how long the shutter stays open, allowing light to pass through the aperture.   The faster the shutter speed the clearer the images – especially with rapidly moving objects.

Exposure is how much light actually gets to the film or digital sensor.  The exposure is determined by the interaction of Aperture and Shutter Speed.   

Focus affects the camera lens and determines the distance at which objects will appear sharp and clear.

Well the 4 basic operations of photography are:

1.) Exposure: Exposure is basically how long the film/paper is being exposed or shown under the light.

2.) Aperture: Also known as the (f-stop) this is what helps control how clear and crisp your pictures are going to turn out.

3.) Focus: This is also similar to aperture, but this is how clear your objects are going to be.

4.) Shutter Speed: This is going to be how long your shutters are going to stay open and it affects how much light is going to be on your film/paper.
