Understanding Exposure for Photography and Film



Understanding Exposure:

Exposure is a critical concept in photography and videography. When you refer to exposure, you're referring to how much light reaches (or is exposed to) the film or camera sensor when capturing an image. Adjusting your camera's exposure settings will determine how light or dark your image is in addition to its clarity. 

The main exposure settings you will use are: Aperture, Shutter Speed, ISO and White Balance
