Single Shot AF is standard and locks onto the subject until you take the picture. AL Focus is used when you can follow a moving object with the camera with the shutter button pressed half way. At the desired moment you take the photo. The moving object will be in focus. AL Servo shot AF is a combination of the two.

== Depth of Field ==
The area of acceptable sharpness in a photo is know as “Depth of Field”. The Depth of Field is achieved through the size of the lens aperture. The aperture itself can be also be referred to as the iris which is the opening within the lens that the light travels through.
Notation for lenses apertures is expressed as f stops.The scale is f1, f1.4, f2, f2.8, f3.5, f4, f5.6, f8, f11, f16, f22, f32, f45, f64. Most lenses operate in the middle of this range. These numbers are a ratio of the actual aperture diameter. A higher f number denotes a smaller aperture. This means that f1 is the largest aperture and f64 is the smallest.
The depth of field (the acceptable sharpness) is expressed as shallow depth of field and extended depth of field (increased sharpness) or increased depth. The mid point between the two is sometimes referred to as average depth of field.

Flash photography is when the main exposure for the image you are taking is based on the flash it self. There can be just one flash or multiple. With multiple flash units one is referred as the main.
