# data[].attributes.body
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

# data[].attributes.body
The aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens

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

# data[].attributes.body
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

# data[].attributes.body
A set of data that describes and gives information about other data

# data[].attributes.body
A technology that helps stabilize the lens movement associated from hand shake which helps eliminate blurry photos resulting from hand shake or too slow of a shutter speed

# data[].attributes.body
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

# data[].attributes.body
One of the main settings on your camera, and it lets you manually control shutter speed, aperture, and ISO

# data[].attributes.body
The fact that you can fiddle with the shutter speed and aperture combo. No matter whether you choose Auto or Program, the camera chooses an aperture and shutter speed combination that will give you a good exposure

# data[].attributes.body
To use Guide Mode, first set the mode dial on top of the camera to GUIDE. Then select "Shoot" from the menu and choose a setting. This simple procedure helps you adjust the camera according to shooting situation and subject

# data[].attributes.body
A setting on some cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure

# data[].attributes.body
ameras will make all the decisions for you, including the aperture setting, the shutter speed, white balance and ISO. Nearly all digital cameras have an automatic exposure mode

# data[].attributes.body
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
Cools down the colors in photos

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

# data[].attributes.body
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
The camera uses to focus on a subject.

# data[].attributes.body
General technique of taking several shots of the same subject using different camera settings.

# data[].attributes.body
A camera viewfinder where the image captured by the lens is projected electronically onto a miniature display. The image on this display is used to assist in aiming the camera at the scene to be photographed.

# 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
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. ... None have lens threads.

# data[].attributes.body
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.

# data[].attributes.body
long exposures at night

# data[].attributes.body
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
A common way of associating the three variables that determine the exposure of a photograph: aperture, shutter speed, and ISO. One must balance all three of these to achieve a desired result, an adjustment of one requiring adjustments of at least one of the others.

# data[].attributes.body
Used to alter exposure from the value selected by the camera, making photographs brighter or darker. In modes P, S, and A, the camera automatically adjusts settings for optimal exposure, but this may not always produce the exposure the photographer intended.

# data[].attributes.body
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.
