Automatic mode is a mode in a digital camera where the camera's software fully controls all aspects of the photograph, from the shutter speed to the aperture setting to the focus.

# data[].attributes.body
Manual-enabled modes give the photographer control over the various parameters of an exposure. ... A or Av: Aperture priority or Aperture value enables manual control of the aperture, and shutter speed is calculated by the camera for proper exposure (given an ISO sensitivity).

# data[].attributes.body
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

TV mode stands for Time Value but is better known as Shutter Priority Mode. In TV mode the user specifies a shutter speed, while the camera adjusts the aperture size to correctly expose the image.

P: Program mode has the camera calculate both shutter speed and aperture (given a manually or automatically selected ISO). ... S or Tv: Shutter priority or Time value enables manual control of the shutter speed, and aperture is calculated by the camera for proper exposure (given an ISO sensitivity).

Noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing. From a physics standpoint, noise is indistinguishable from sound, as both are vibrations through a medium, such as air or water. The difference arises when the brain receives and perceives a sound.

n 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.

At it's most basic, Wikipedia states that film grain is, “Film grain or granularity is the random optical texture of processed photographic film due to the presence of small particles of a metallic silver, or dye clouds, developed from silver halide that have received enough photons.

Autofocus points are what the camera uses to focus on a subject. You'll probably first notice them when you press the shutter halfway. Many cameras will emit a "beep," and some of the AF points will light up (often in a red or green color) in the viewfinder or on the display screen.

bracketing is the general technique of taking several shots of the same subject using different camera settings. ... Autobracketing is automatic bracketing by using a setting on the camera to take several bracketed shots

In manual mode, the exposure level indicatormoves depending on your exposure settings. If you set your exposure settings so that the exposure level indicator is on 0, you'll take the standard exposure. ... As you make changes to shutter speed and aperture, the ISO will automatically adjust to keep the exposure at 0 EV.

Exposure Compensation. Exposure compensation is used to alter exposure from the value selected by the camera, making photographs brighter or darker. In modes P, S, and A, the camera automatically adjusts settings for optimal exposure, but this may not always produce the exposure the photographer intended.

Burst mode, also called continuous shooting mode, sports mode or continuous high speed mode, is a shooting mode in still cameras. In burst mode, several photographs are captured in quick succession by either pressing the shutter button or holding it down

In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles.

In photography, bokeh (/ˈboʊkeɪ/ BOH-kay; Japanese: [boke]) is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light".

1. the distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.

# data[].attributes.body
The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters (e.g., 28 mm, 50 mm, or 100 mm). In the case of zoom lenses, both the minimum and maximum focal lengths are stated, for example 18–55 mm.

White Balance. White balance is a feature many digital cameras and video cameras use to accurately balance color. ... Since different types of lighting affect the way a camera's sensor captures color, most digital cameras and camcorders include an auto white balance (AWB) setting.
