I . EXPOSURE
Exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region.

II . APERTURE
Aperture is measured using something called the f-stop scale. On your camera, you’ll see ‘f/’ followed by a number.
The number denotes how wide the aperture is which, in turn, affects the exposure and depth of field (also tackled below) – the lower the number, the wider the aperture.

III . SHUTTER SPEED
A camera's shutter determines when the camera sensor will be open or closed to incoming light from the camera lens. The shutter speed specifically refers to how long this light is permitted to enter the camera. "Shutter speed" and "exposure time" refer to the same concept, where a faster shutter speed means a shorter exposure time.

IV . COMPOSITION
Composition is defined as the combining of distinct parts or elements to form a whole. In photography that definition is very important in taking quality pictures. The following rules of composition should be learned and considered but not necessarily used in every photo. Once you have learned these rules you will be more observant of the possible photo opportunities that surround you. But keep in mind that the really famous photographers usually find a creative way to stretch or break the rules of composition.
V . RULE OF THIRD
The rule of thirds has been used through the centuries and is probably the most recognized rule. The rule of thirds directs that the frame can be divided into three vertical sections and three horizontal sections. Wherever the separating lines connect is an ideal spot for a subject or point of interest. By positioning your main subject at any of the four intersection points, you are giving your subject more emphasis than If it is right in the middle of the photo. The intersection points can also work if there is more than one main subject in a photo. Most famous photographs and paintings have the rule of thirds applied to them in some way or another.

VI . DEPTH OF FIELD
In optics, particularly as it relates to film and photography, depth of field (DOF), also called focus range or effective focus range, is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.

VII . BALANCE
Balance is a compositional technique in photography that juxtaposes images within a frame so that the objects are of equal visual weight. When different parts of a photo command your attention equally, perfect balance is achieved.

VIII . LIGHTNING
Photographic lighting is the illumination of scenes to be photographed. A photograph simply records patterns of light, colour, and shade; lighting is all-important in controlling the image. In many cases even illumination is desired to give an accurate rendition of the scene.
