adjusted to control the amount of light reaching the film or image sensor. In combination with variation of shutter speed, the aperture size will regulate the film's or image sensor's degree of exposure to light.

the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light

# data[].attributes.body
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, for example 18–55 mm.

one of the main settings on your camera, and it lets you manually control shutter speed, aperture, and ISO. ... The auto modes (Auto, Program), and semi automatic modes (Aperture Priority, and Shutter Priority) on your camera are great places to start.

# data[].attributes.body
calculate both shutter speed and aperture (given a manually or automatically selected ISO). ... A or Av: Aperture priority or Aperture value enables manual control of the aperture, and shutter speed is calculated by the camera for proper exposure

# data[].attributes.body
With this setting the camera will decide what the correct white balance is for the scene it sees through the lens. It will adjust the white balance for each picture you take, so you may not have consistent color

# data[].attributes.body
This type of lighting is gradually being phased out. The old standard incandescent light bulb gets hot and uses too much energy.

# data[].attributes.body
As mentioned earlier, fluorescent light has a deficit of blue, so your subjects will come out looking greenish

# data[].attributes.body
When you are shooting outside under direct sunlight, the color is somewhat neutral and tends to be warm. Using this setting will balance your camera for shooting under direct sunlight

# data[].attributes.body
When you use a flash unit, whether it’s a popup unit built into your camera or an external unit mounted on your camera, you can set the white balance to flash and the camera will record consistent color for most flash units.

# data[].attributes.body
On a cloudy or overcast day the light has a blue tint that can make images seem cool. When you set the camera to cloudy white balance, it adds red (warmth) to the image so it looks more natural.

:comparative darkness or obscurity owing to interception of the rays of light. b :relative obscurity or retirement.

# data[].attributes.body
Many beginning photographers are taught to use the center autofocus point, obtain focus while pointing that center focus point on the eye, and then recomposing so the eye is placed according to the rule of thirds. This technique is called focus and recompose.

# data[].attributes.body
the general technique of taking several shots of the same subject using different camera settings. ... Auto bracketing is automatic bracketing by using a setting on the camera to take several bracketed shots

# data[].attributes.body
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
device used to measure the amount of light. ... Typically a light meter will include either digital or analog electronic circuit, which allows the photographer to determine which shutter speed and f-number should be selected for an optimum exposure, given a certain lighting situation and film speed.

# data[].attributes.body
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. ... None have lens threads.

# data[].attributes.body
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
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

# 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
cannot support a camera independently. In the case of still cameras, this limits the shutter speed that can be used. They still allow lower shutter speeds than hand holding, and are easier to carry and use than a tripod.

# data[].attributes.body
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
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
the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance.

# 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
technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that used to view the sequence. When played at normal speed, time appears to be moving faster and thus lapsing.

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
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
the detail animage holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail. Image resolution can be measured in various ways.

They are small, ultra-wide, and show a distorted, spherical view of the world, most evident in the curved, outer corners of the photo. Fisheye lenses happen to work very well underwater for a couple different reasons: They focus very closely. There are few straight lines underwater.

It's important to know what shadows, midtones and highlights are in photographic terms when it comes to using Photoshop. ... Shadows are the darkest areas of a photograph. A shadow is also devoid of color; it could be the black in a photograph or just the areas that carry little light.

# data[].attributes.body
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.

# data[].attributes.body
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.
