Understanding aperture
- What is aperture?: The size of the opening in the lens when a picture is taken.
- How aperture works both technically (in camera) and visually (in photo)?: It opens and closes, it is the length of time the film is exposed to light. Visually, it creates blur in the background when using a wide aperture and using the camera to lens for focus.
- The relationship to the exposure triangle?: The 3 parts are aperture, shutter speed, ISO and when you change one you have to the others also to get a good photograph.
