Exposing Correct Exposure
Understanding exposure in photography can be quite confusing and there are endless tutorials and articles written to help. Exposure is critical to capturing perfect photos as in a nutshell exposure equates to how light or dark your photo is. Good exposure will show a photo with whites that are not too dark or too bright and blacks that are not too black but not to light. On a histogram good exposure can look a little like this.
There are 3 elements to obtaining the right exposure – ISO, Aperture and Shutter Speed. In the most basic terms:
ISO = how sensitive your camera is to light
Aperture = the size of the hole that lets light into your camera
Shutter Speed = the speed in which the hole is open to let light into your camera.
