An exposure mode on an automatic or autofocus camera that lets you set the aperture while the camera sets the shutter speed for proper exposure. If you change the aperture, or the light level changes, the shutter speed changes automatically.
Some cameras have an Aperture Priority setting. This setting allows the user to select the aperture they wish and the camera picks the corresponding shutter speed based on the light readings. See also: Shutter Priority | Light Meter
With an automatic camera, it is possible to set the aperture and have the camera choose the corresponding shutter speed for a correct exposure. This is particularly useful for times when you need to control depth of field.
(see also Shutter Priority) An automated exposure system designed to give preference to the aperture selected by the photographer. The exposure system will adjust the shutter speed, as needed, to give proper exposure.
Defining camera's aperture by leaving calculation of shutter speed to the camera's automatic mechanism.
A mode in which a desired lens opening [f -stop] is manually selected and looked in, the camera then chooses an appropriate shutter speed for proper exposure.
The ability to change the aperture setting in an automatic or autofocus camera. By changing the aperture, it either increases or decreases the amount of light let into expose the film. With automatic cameras, once you change the aperture – the shutter speeds adjusts accordingly.
A semi automatic exposure setting, allowing the photographer to choose the aperture setting of the camera lens, while the metering system of the camera automatically selects the correct shutter speed for prevailing light conditions. See Exposure.
Aperture Priority Auto Exposure, (A mode) when the user sets the aperture and the auto camera sets the most appropriate shutter speed. Most used mode as it is the appropriate for accurate depth of field control. Since the exposure decision is not entirely left to the camera's onboard computer, this is referred to as a semi-auto mode.
A larger aperture (opening) allows more light for a brighter image. This is very useful when taking pictures at night or in a dark room. Reducing the aperture can control light in environments that may be too bright. During Aperture Priority Mode on Toshiba Digital Cameras the Shutter and Flash are automatically set to optimize performance.
In this mode, the user can adjust the aperture and the camera automatically selects the best shutter speed to match it. In most cameras, the Aperture Priority mode is denoted by the letter "A". Shutter Priority.
An exposure mode that lets you set the aperture while the camera sets the shutter speed for the correct exposure.
Feature of a camera where the aperture is set to a fixed f-stop, and the camera chooses the corresponding shutter speed for a correct exposure. This is useful for controlling the depth of field.
A function or shooting mode of a semi-automatic camera that permits the photographer to preset the aperture and leaves the camera to automatically determine the correct shutter speed. What does that mean? You select the aperture setting you want and the camera then automatically calculates the appropriate corresponding shutter speed for proper exposure. It's like a fully-automatic camera except you totally control the aperture.
Is an exposure mode, that lets you set the aperture, while the camera sets the shutter speed automatically. This means, that if you change the aperture, (or the light level changes) the shutter speed will change automatically or in other words: The Aperture priority auto exposure system allow you to set the lens aperture and the camera automatically set the shutter speed to match this.
Aperture priority, abbreviated Av or A, is a setting on some cameras that allows the user to chose an aperture while the camera selects a shutter speed to match. The camera will ensure proper exposure. This is different from manual mode, where the user must decide both values, shutter priority where the user picks a shutter speed with the camera selecting the aperture to match, or program mode where the camera selects both.
