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.

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 cameraselects a shutter speed to match it that will result in proper exposure based on the lighting conditions

# data[].attributes.body
Tv (or S) stands for “Shutter Priority Mode” ... Tv is a “priority” mode that lets you specify a shutter speed and leaves the camera to figure out everything else

# 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

In Digital Photography ISO measures the sensitivity of the image sensor.

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

In photography, ASA and ISO are both measurements of film speed, or sensitivity to light.

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 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.

Metadata is a set of data that describes and gives information about other data. Photo metadata allows 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.

A thumbnail image is a small image that represents a larger one. Thumbnails are often used to provide snapshots of several images in a single space. They are commonly used by digital photo organization programs as well as visual search engines.

Autofocus points are what the camera uses to focus on a subject.

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.

In photography, bracketing is the general technique of taking several shots of the same subject using different camera settings

# data[].attributes.body
Exposure compensation is used to alter exposure from the value selected by the camera, making photographs brighter or darker.

# data[].attributes.body
In burst mode, several photographs are captured in quick succession by either pressing the shutter button or holding it down.

# data[].attributes.body
The f-stop of a lens is determined by dividing the focal length of the lens by ... The wider the aperture (f-stop), the shorter the shutter speed, and vice versa

# data[].attributes.body
You can shrink or enlarge the size of the aperture to allow more or less light to reach your camera sensor. ... The technical definition of aperture is: “The opening in a lens through which light passes to enter the camera.”

# data[].attributes.body
Bokehis defined as “the effect of a soft out-of-focus background that you get when shooting a subject, using a fast lens, at the widest aperture

the optical phenomenon known as depth of field, is the distance about the plane of focus where objects appear acceptably sharp in an image.

shutter speed refers to the length of time a camera shutter ... For example 1/4 means a quarter of a second

# data[].attributes.body
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

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.

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.

shadows are an entity as alive as the light. It is the shadows that shape the light, draw attention to the light, and integrate with the light to produce striking photographic opportunities.

Time-lapse photography is a technique whereby the frequency at which film frames are captured (the frame rate) is much more spread out than the frequency used to view the sequence. When played at normal speed, time appears to be moving faster and thus lapsing.
