a setting on some cameras that allows the user to set a specific aperture value (f-number) while the camera selects ashutter speed to match it that will result in proper exposure based on the lighting conditions.

The f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil.

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 (given a manually or automatically selected ISO).

White balance (WB) is the process of removing unrealistic color casts, so that objects which appearwhite in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light.

Fluorescence photography, process that records the glow or visiblelight given off by certain substances when they are irradiated by ultraviolet rays.

(Autofocus points) Autofocus points are what the camera uses to focus on a subject. You'll probably first notice them when you press the shutter halfway. Many cameras will emit a "beep," and some of the AF points will light up (often in a red or green color) in the viewfinder or on the display screen.

In photography, bracketing is the general technique of taking several shots of the same subject using different camera settings. Autobracketing is automatic bracketing by using a setting on the camera to take several bracketed shots (in contrast to the photographer altering the settings by hand between each shot).

An electronic viewfinder (EVF) is 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.

Shutter speed is the unit of measurement which determines how long shutter remains open as the picture is taken. The slower the shutter speed, the longer the exposure time. The shutter speed and aperture together control the total amount of light reaching the sensor.

This means 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 (displayed 30″ on the camera) that is allowed on most DSLRs.

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.

A tripod is used to stabilize and elevate a camera, a flash unit, or other photographic equipment. All photographic tripods have three legs and a mounting head to couple with a camera. ... Tripods are usually made from aluminum, carbon fiber, steel, wood or plastic.

A monopod does not provide camera stability in the same way that a tripod does. Aphotographer uses a monopod to help support and balance the camera, giving more control of the camera position than what would be possible when shooting by hand.

Light painting, or light drawing, is a photographictechnique in which exposures are made by moving a hand-held light source while taking a long exposurephotograph, either to illuminate a subject or to shine a point of light directly at the camera, or by moving the camera itself during exposure.

The exposure triangle is 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.

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.

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.

Time-lapse photography is a 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.

Long-exposure, time-exposure, or slow-shutterphotography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving elements.

In photography and computing, a grayscale or greyscale digital image is an image in which the value of each pixel is a single sample, that is, it carries only intensity information. ... Grayscale images have many shades of gray in between.
