Exposure | Boomer Web School


You can adjust the exposure of a photo by selecting the sunburst icon, and sliding it up or down. That will either lighten or darken the photo.

Official definition: 
In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance. https://en.wikipedia.org/wiki/Exposure_(photography)
