# data[].attributes.body
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.

# data[].attributes.body
determined by dividing the focal length of the lens by the diameter of the size of entrance pupil, i.e., the lens opening

# data[].attributes.body
a space through which light passes in an optical or photographic instrument, especially the variable opening by which light enters a camera.

# data[].attributes.body
the blurred quality or effect seen in the out-of-focus portion of a photograph taken with a narrow depth of field

# data[].attributes.body
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.

# data[].attributes.body
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.

# data[].attributes.body
a standard that specifies formats for files recorded by digital cameras. None of this information is added by the user at the time of file creation.

# 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
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.

# data[].attributes.body
it lets you manually control shutter speed, aperture, and ISO

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

# data[].attributes.body
This setting uses exposure compensation to take an underexposed image and is used for taking photos of darker objects.

# data[].attributes.body
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
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 aperturesetting to the focus.

# 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
what 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
is a camera viewfinder where the image captured by the lens is projected electronically onto a miniature display.

# data[].attributes.body
a device used to measure the amount of light.

# data[].attributes.body
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
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

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

# 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.

# data[].attributes.body
is used in the video/film business for quality-improvement image processing

# data[].attributes.body
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.

# data[].attributes.body
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

# data[].attributes.body
is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation.

# data[].attributes.body
three legged stands that nearly all photographers have while nopods have one leg.

# data[].attributes.body
is a photographictechnique 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
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
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);

# data[].attributes.body
is a special type of ultra-wide angle lens. They are small, ultra-wide, and show a distorted, spherical view of the world, most evident in the curved, outer corners of the photo

# data[].attributes.body
is caused by movement of the camera(hence the name :-)), which becomes noticeable as blur when using a slow shutter speed.

# data[].attributes.body
to photograph or televise while rotating a camera on its vertical or horizontal axis in order to keep a moving person or object in view or allow the film to record a panorama

# data[].attributes.body
a range of gray shades from white to black, as used in a monochrome display or printout.

# data[].attributes.body
a dark reddish-brown pigment obtained from the inky secretion of the cuttlefish

# data[].attributes.body
That range of tones which lie between highlights with detail and shadows with detail.

# data[].attributes.body
bright spot in a photograph. Normally it is assumed to be one of the brightest points in the image

# data[].attributes.body
A shadow will change in shape, definition, and color based on the positioning, quality, and color of the light creating it.
