The exposure triangle is a relatively new term first bursting onto the scene somewhere between 2005 and 2010. Before that, it was “time + intensity = exposure.” With digital cameras and their ability to change ISO values, that old…

ISO ISO is the final part of the exposure triangle. It controls the sensitivity (or gain) of your recording medium. The important thing to remember with ISO is that the lower the number, the less grain or noise your image will have. Your film or sensor will also be less sensitive so you will either…
Shutter Speed
Shutter Speed Shutter speed, along with aperture and ISO, is part of the exposure triangle. Shutter speeds are almost always written in seconds or fractions of a second. There are a few main types of shutters, which are covered in the shutter section. They all function slightly differently but their main goal is to control…

Aperture controls: First and foremost, the aperture’s main function is to control the amount of light entering the camera by increasing or decreasing the size of the hole. …
