# data[].attributes.body
Definition:  refers to 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.

Definition: an aspect of photography that many digital camera owners don’t understand or use – but it’s something well worth learning about as it can have a real impact upon the shots you take.

Definition: selection is combined with AI Servo AF, the active AF points will not light up red in the viewfinder. This mode allows you to manually select any of the available AF points to use for focusing on your subject

# data[].attributes.body
Definition:the process of taking three photos; one using the camera's recommended settings, one intentionally underexposed, and one intentionally overexposed.

# data[].attributes.body
Definition: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
definition: measure the amount of light falling on a subject and work best when held in front of the subject and aimed at the light source.

# data[].attributes.body
Definition: a still camera designed primarily for simple operation

# data[].attributes.body
definition:shutter speed or 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
definition: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 (displayed 30″ on the camera) that is allowed on most DSLRs.

# data[].attributes.body
Definition: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
Definition: used to stabilize and elevate a camera

# data[].attributes.body
Definition: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
Definition: 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
Definition: 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
Definition:a shooting mode in still cameras. In burst mode, several photographs are captured in quick succession by either pressing the shutter button or holding it down.[1] This is used mainly when the subject is in successive motion, such as sports photography. The photographer can then select the best image of the group or arrange them in a sequence to study the transitions in detail.

# data[].attributes.body
Definition: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
Definition: used in the video/film business for quality-improvement image processing (specifically digital image processing) methods used in video playback devices, (such as stand-alone DVD-Video players), and video players software and transcoding software.

# data[].attributes.body
Definition: 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
Definition:measured in megapixels (meaning millions of pixels); both image ﬁle resolution 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) (

Definition:A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view.

# data[].attributes.body
Definition: blurring associated with the motion of a camera or other imaging device during exposure.

Definition: Photographing Moving Subjects. ... The basic idea behind panning as a technique is that you pan your camera along in time with the moving subject and end up getting a relatively sharp subject but a blurred background. This gives the shot a feeling of movement and speed.

Definition:a range of gray shades from white to black, as used in a monochrome display or printout.

# data[].attributes.body
Definition:a reddish-brown color associated particularly with monochrome photographs of the 19th and early 20th centuries.

# data[].attributes.body
Definition: range of tones which lie between highlights with detail and shadows with detail. * Usually represents the portion of tone reproduction in which gradations change in proportion to change in brightness. * Compare with mid-tone.

# data[].attributes.body
Definition:A highlight is a bright spot in a photograph. Normally it is assumed to be one of the brightest points in the image. Highlights are normally created by a bright or intense illumination or by various forms of diffusion or reflection. Highlights are created by any bright light source.

Definition:A shadow is a dark area where light from a light source is blocked by an opaque object. It occupies all of the three-dimensional volume behind an object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.
