Camera and Manual Settings

Alex Clare

Aperture• An aperture is a hole or an opening

through which light travels. More specifically, the aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane.

Shutter Speed

• The camera's shutter speed, the lens's brightness together determine the amount of light that reaches the film or sensor. Exposure value is a single quantity that accounts for the shutter speed and the f-number.

ISO

• ISO is similar to film speed on film cameras. Unlike aperture and shutter speed, ISO doesn't control how much light enters the camera, but instead controls how sensitive the camera is to that light. The lower the ISO, the less sensitive the camera is. In other words, a lower ISO will require more light to properly expose a picture than a higher ISO.
