The exposure Triangle

Aperture

Aperture is represented by “AV” which on the camera says Aperture priority AE. In photography Aperture controls the brightness of the image that passes through the lens and falls on the image sensor. It is expressed as an f-number (written as “f/” followed by a number), such as f/1.4, f/2, f/2.8, /f4, f/5.6, f/8, f/11, f/16, f/22, or f/32.

Shutter Speed

Shutter Speed is represented as “TV” which on the camera shutter priority  AE. In photography, shutter speed is the unit of measurement which determines how long shutter remains open as the picture is taken. The slower the shutter speed, the longer the exposure time. The shutter speed and aperture together control the total amount of light reaching the sensor.

ISO

ISO is the same on the camera as it is seen written. It stands for international Organisation of Standardisation.The term was carried over from film, when the ISO rating was known as the “film speed” and “ASA.”ISO in Digital Photography. In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain.

Rule of Thirds

Rule of Thirds is supposed to create drama and helps to build interest in a photo.

Example:

We tried to incorporate the rule of thirds into some of are photos by using different sides of the photograph.
