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.

The general process of shooting in manual modemight look something like this: Check the exposure of your shot with the light meter visible through your viewfinder. Pick an aperture. Adjust the shutter speed.

# data[].attributes.body
It is the mode that most hobbyist photographers and even many many pro photographers shoot in most of the time. When you shoot aperture priority mode, you set the aperture (the f-stop) and also the ISO.

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). ... 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).

ISO in Digital Photography. 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.

Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise.

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

# data[].attributes.body
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 (also called digital SLR or DSLR) 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.

Definition, Types, and Relevance. Metadata is a set of data that describes and gives information about other data. Photo metadataallows information to be transported with an image file, in a way that can be understood by other software, hardware, and end users, regardless of the format.

Thumbnails are reduced-size versions of pictures or videos, used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words.

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 focus on a subject. You'll probably first notice them when you press the shutter halfway

The f-number of an optical system is the ratio of the system's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. It is also known as the focal ratio, f-ratio, or f-stop.

# data[].attributes.body
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.

# data[].attributes.body
In optics, particularly as it relates to film and photography, the optical phenomenon known as depth of field, is the distance about the plane of focus where objects appear acceptably sharp in an image.

# data[].attributes.body
Focal Length and Angle of view. 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 is a feature many digital cameras and video cameras use to accurately balance color.

Light that comes more or less directly from sun: it varies very widely in brightness, colour and quality.

# data[].attributes.body
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.

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.

1. the time for which a shutter is open at a given setting.

# data[].attributes.body
is an exposure setting that is used when seeking to use a shutter speed of more than 30 seconds. Generally, this would be used in extremely low light situations, such as taking photos of the night sky.

# data[].attributes.body
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

# data[].attributes.body
a tripod is used to stabilize and elevate a camera, a flash unit, or other photographic equipment. All photographic tripodshave three legs and a mounting head to couple with a camera.

Camera shake is a term used to define the act of accidentally shaking a cameraduring 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.
