an exposure system used in some automatic cameras in which the aperture is selected by the user and the appropriate shutter speed is controlled automatically.

an opening, hole, or gap.

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

# data[].attributes.body
the distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.

A digital single-lens reflex camera (also called a 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.

a set of data that describes and gives information about other data.

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

a very small or concise description, representation, or summary.

Manual mode is one of the main settings on your camera, and it lets you manually control shutter speed, aperture, and ISO...

# data[].attributes.body
Program mode has the camera calculate both shutter speed and aperture

# data[].attributes.body
Shutter priority refers to a setting on some cameras that allows the user to choose a specific shutterspeed while the camera adjusts the aperture to ensure correct exposure.

# data[].attributes.body
In automatic mode the cameras will make all the decisions for you, including the aperture setting, the shutter speed, white balance and ISO.

# data[].attributes.body
this is where the camera makes a best guess on a shot by shot basis. You’ll find it works in many situations but it’s worth venturing out of it for trickier lighting.

# data[].attributes.body
this mode is usually symbolized with a little bulb and is for shooting indoors, especially under tungsten (incandescent) lighting (such as bulb lighting). It generally cools down the colors in photos.

# data[].attributes.body
this compensates for the ‘cool’ light of fluorescent light and will warm up your shots.

# data[].attributes.body
not all cameras have this setting because it sets things as fairly ‘normal’ white balance settings

# data[].attributes.body
the flash of a camera can be quite a cool light so in Flash WB mode you’ll find it warms up your shots a touch.

# data[].attributes.body
this setting generally warms things up a touch more than ‘daylight’ mode.

# data[].attributes.body
the light in shade is generally cooler (bluer) than shooting in direct sunlight so this mode will warm things up a little.

# data[].attributes.body
Autofocus points are what the camera uses to focus on a subject. You'll probably first notice them when you press the shutter halfway.

# data[].attributes.body
In photography, bracketing is the general technique of taking several shots of the same subject using different camera settings.

# data[].attributes.body
An electronic viewfinder (EVF) is a camera viewfinder where the image captured by the lens is projected electronically onto a miniature display.

# data[].attributes.body
an instrument for measuring the intensity of light, used chiefly to show the correct exposure when taking a photograph.

# data[].attributes.body
A point-and-shoot camera, also known as compactcamera, is a still camera designed primarily for simple operation. Most use focus free lenses or autofocus for focusing, automatic systems for setting the exposure options, and have flash units built in

# data[].attributes.body
the time for which a shutter is open at a given setting.

# data[].attributes.body
Bulb mode is a shooting mode found on some cameras. With the camera set to bulb mode, the shutter will stay open as long as it is pressed, rather than releasing for a designated amount of time.

# data[].attributes.body
Motion blur is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation. It results when the image being recorded changes during the recording of a single exposure, either due to rapid movement or long exposure.

# data[].attributes.body
A monopod is a single pole that is used to support a camera. A tripod is a three-legged frame that is used to stabilize a camera. Neither should ever be substituted for the other, and any serious photographer will have both a monopod and a tripod.

# data[].attributes.body
Light painting, or light drawing, is a photographic technique in which exposures are made by moving a hand-held light source while taking a long exposure photograph, either to illuminate a subject or to shine a point of light directly at the camera, or by moving the camera itself during exposure.

# data[].attributes.body
The exposure triangle is a common way of associating the three variables that determine the exposure of a photograph: aperture, shutter speed, and ISO.

# data[].attributes.body
Exposure compensation is the control by which you temporarily adjust your camera's definition of what is "properly exposed". Put simpler, it's a way to force the camera to make your photos darker or brighter to the degree that you tell it.

# data[].attributes.body
In burst mode, several photographs are captured in quick succession by either pressing the shutter button or holding it down. This is used mainly when the subject is in successive motion, such as sports photography.

# data[].attributes.body
denoting the photographic technique of taking a sequence of frames at set intervals to record changes that take place slowly over time. When the frames are shown at normal speed, or in quick succession, the action seems much faster.

Post-processing may refer to: Image editing in photography. Audio editing software in audio. Differential GPS post-processing, an enhancement to GPS systems that improves accuracy. Video post-processing, methods used in video processing and 3D graphics.

# data[].attributes.body
Long-exposure, time-exposure, or slow-shutter photography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving elements.

# data[].attributes.body
Camera resolution is measured in megapixels (meaning millions of pixels); both image ﬁleresolution and monitor resolution are measured in either pixels per inch (ppi) or pixel dimensions (such as 1024 by 768 pixels); and printer resolution is measured in dots per inch (dpi) (see below).

Unintentional slight movement of a camera during photography or filming, liable to cause blurring of the image.

a reddish-brown color associated particularly with monochrome photographs of the 19th and early 20th centuries.

When using pastel, an artist may often use a colored paper support, using areas of pigment to define lights and darks, while leaving the bare support to show through as the mid-tone.
