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. ... As knowledge of photography is increased, most people look towards the two semi-automatic exposure modes called aperture priority and shutter priority (AV, TV).

# 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 by the camera's light meter. 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 an appropriate aperture, or program mode where the camera selects both.

# data[].attributes.body
When your camera mode dial is set on AV, your camera is in Shutter Priority Mode (S is used instead of TV on Nikon and many other cameras). In TV, the user manually chooses a shutter speed setting while the camera automatically adjusts the aperture for each shot.

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).

In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain. ... By choosing a higher ISO you can use a faster shutter speed to freeze the movement.

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 is an undesirable by-product of image capture that obscures the desired information.

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.

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. ... It can be objectionably noticeable in an over-enlarged photographic film photograph.

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 imagingdevice 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. The reflex design scheme is the primary difference between a DSLR and other digital cameras.

Image metadata is text information pertaining to an image file that is embedded into the file or contained in a separate file that is associated with it. Image metadataincludes details relevant to the image itself as well as information about its production. ... Metadata can also be added directly on some digital cameras.

Thumbnail is a term used by graphic designers and photographers for a small image representation of a larger image, usually intended to make it easier and faster to look at or manage a group of larger images. ... Adobe's Photoshop lets you view a thumbnail version of certain kinds of images.

Vibration Reduction (VR) is an image stabilization technology that minimizes blur caused by camera shake. ... Nikon VR originates inthe lens, not in the image sensor, which means that algorithms optimized to an individual lens are applied.

White balance is a feature many digital cameras and video cameras use to accurately balance color. It defines what the color white looks like in specific lighting conditions, which also affects the hue of all other colors. Therefore, when the white balance is off, digital photos and recordings may appear to have a certain hue cast over the image.

Most photographers know that a cloudy or overcast day produces really soft light that can be flattering on the human face. ... Sometimes Most of the time overcast light is actually pretty boring and removes any and all contrast from your scene.

In photography, Tungsten light 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.

: a usually tubular electric lamp having a coating of fluorescent material on its inner surface and containing mercury vapor whose bombardment by electrons from the cathode provides ultraviolet light which causes the material to emit visible light.

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. ... Flash units are commonly built directly into a camera.

The photographic art you choose to place on your wall is ultimately the result of the vision of the photographer. This vision, coupled with what you wear to your session, the environment, the lighting, even the mood the subjects are in at the time of photographing creates the work that you will want to proudly display on your walls forevermore.

In photography, shutter 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.

This means the camera will keep taking a picture until your finger comes off the shutter button. Bulb mode is mostly used for long exposures at night. The main advantage is that it allows the photographer to achieve shutter speeds longer than the 30 seconds (displayed 30″ on the camera) that is allowed on most DSLRs.

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.

In photography, a tripod is used to stabilize and elevate a camera, a flash unit, or other photographic equipment. All photographic tripods have three legs and a mounting head to couple with a camera.
Unlike a tripod, monopods cannot support a camera independently. In the case of still cameras, this limits the shutter speed that can be used. ... Many monopods can also be used as a "beltpod,"meaning that the foot of the monopod can rest on the belt or hip of the photographer.

Camera shake is a term used to define 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.
