Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a setting on some cameras that allows the user to set a specific aperture value (f-number) while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by ...

Definition: Used colloquially in the context of film photography, ISO followed by a number (e.g., 400) represented the sensitivity of a given film emulsion to light, often referred to as "film speed." ... When changing the ISO on a digital imaging device, the gain is changed rather than the sensitivity of the image sensor.

Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the sensor and circuitry of a scanner or digital camera. Image noise can also originate in film grain and in the unavoidable shotnoise of an ideal photon detector.

In photography, ASA and ISO are both measurements of film speed, or sensitivity to light. ASA is a scale created by the American Standards Association, but it is no longer widely used. Now, most film is labeled by ISO, which was created in 1987 by the International Organization for Standardization.
