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 mode on a camera allows the photographer to determine the exposure of an image by letting them select an aperture value and a shutter speed value.

# 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)

# data[].attributes.body
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.

# data[].attributes.body
Program mode has the camera calculate both shutter speed and aperture (given a manually or automatically selected ISO)

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.

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.

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.

An image sensor is an electronic device that converts an optical image into an electronic signal. It is used in digital cameras and imaging devices to convert the light received on the camera or imaging device lens into a digital image.

A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.

Vibration Reduction (Nikon) and Image Stabilization (Canon) is the name of a technology that helps stabilize the lens movement associated from hand shake. These stabilizers help eliminate blurry photos resulting from hand shake or if you're shutter speed is too slow.

Autofocus points are what the camera uses to focuson 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.

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 contrast to the photographer altering the settings by hand between each shot).

Your digital camera has an exposure level indicatorscale (a.k.a. exposure scale or exposure meter), shown here. ... The numbers to the left and right of center tell you how many stops — or levels ofexposure value (EV) — you are away from the center.

# data[].attributes.body
Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image.

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

The focal length of an optical system is a measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus.

refers to an artificial lighting source (like a lamp or ceiling fixture) that emits heat and produce a “warmer” or reddish colour. It is distinguished from fluorescent lighting (which generates much lower heat), and strobe lighting.

# data[].attributes.body
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescenceto produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.

A flash is a device used in photography producing a flash of artificial light (typically 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene. A major purpose of a flash is to illuminate a dark scene.

hutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time.

The Bulb setting on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button.

Motion blur is the apparent streaking of moving objects in a photograph or a sequence of frames, such as a film or animation. It results when the image being recorded changes during the recording of a single exposure, due to rapid movement or long exposure.

The act of accidentally shaking a camera during shooting due to unsteady hands, which results in blurry images. This generally occurs more often if you're shooting on a low shutter speed or with a heavy lens, and can be avoided by using a tripod and cable release setup.

Light painting, painting with light, light drawing, or light art performance photography are terms that describe photographic techniques of moving a light source while taking a long exposure photograph, either to illuminate a subject or space, or to shine light at the camera to 'draw'.

The basic idea behind panning as a technique is that you pan your camera along in time with the moving subject and end up getting a relatively sharp subject but a blurred background. This gives the shot a feeling of movement and speed.

Digital cameras are identiﬁed based on their resolution, which is measured in megapixels. This term is simply a measure of how many millions of pixels the camera's image sensor captures to produce the digital image.
