How does the relationship between ISO, shutter speed/angle, and aperture determine the quality of your footage? The camera’s exposure determines how much light shows through your picture or video. If you want your image or video to appear light or dark when you capture the footage, you will need to adjust the exposure. Controlling the ISO, aperture, and shutter speed, also known as the trifecta setup, controls the exposure. In this clip from our video content course, we explain how each element works together to achieve the desired exposure for the footage.
