Exposure:
In photography, 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.

Aperture:
A device that controls the amount of light admitted through an opening.
In photography and digital photography, aperture is the unit of measurement
that defines the size of the opening in the lens that can be adjusted
to control the amount of light reaching the film or digital sensor

Shutter Speed:
In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph.
Composition:
In the visual arts—in particular painting, graphic design, photography, and sculpture--composition is the placement or arrangement of visual elements or ingredients in a work of art, as distinct from the subject of a work
Rule of Third:
The guideline proposes that an image should be imagined as divided into nine equal parts by two equally spaced horizontal lines and two equally spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections.
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.
Balance:
Balance is a photography technique that involves capturing images within a frame so all parts of the image have equal visual weight. Proper balance should increase the visual appeal of a photograph. There are generally two types of balance, formal and informal.
