In automatic mode the cameras 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. Other digital camera settings and shooting modes include: Macro mode to focus on subjects close to the camera lens.

Manual mode on a camera allows the photographer to determine the exposure of an image by letting them select an aperture value and a shutter speed value. ... As knowledge of photography is increased, most people look towards the two semi-automatic exposure modes called aperture priority and shutter priority (AV, TV).

# data[].attributes.body
Aperture priority, often abbreviated A or Av (for aperture value) on a camera modedial, is a setting on some cameras that allows the user to set a specific aperture value (f-number) while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by

When your camera mode dial is set on AV, your camera is in Shutter Priority Mode(S is used instead of TV on Nikon and many other cameras). In TV, the user manually chooses a shutter speed setting while the camera automatically adjusts the aperture for each shot.

Use Program Mode to Control Action and Depth of Field. The "program" in Program mode refers to the fact that you can fiddle with the shutter speed and aperturecombo. Whether you choose Auto or Program, the camera chooses an apertureand shutter speed combination that will give you a good exposure.

In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain.

Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the sensor and circuitry of a scanner or digital camera.

In photography, ASA and ISO are both measurements of film speed, or sensitivity to light. ASA is a scale created by the American Standards Association, but it is no longer widely used.

Film grain or granularity is the random optical texture of processed photographic film due to the presence of small particles of a metallic silver, or dye clouds, developed from silver halide that have received enough photons

An image sensor is an electronic device that converts an optical image into an electronic signal. It is used in digital cameras and imaging devices to convert the light received on the camera or imagingdevice lens into a digital image.

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

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 photography, exposure is the amount of light which reaches your camera sensor or film. It is a crucial part of how bright or dark your pictures appear. There are only two camera settings that affect the actual “luminous exposure” of an image: shutter speed and aperture.

# data[].attributes.body
Exposure compensation is 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.

Aperture controls the brightness of the image that passes through the lens and falls on the image sensor. It is expressed as an f-number (written as “f/” followed by a number), such as f/1.4, f/2, f/2.8, /f4, f/5.6, f/8, f/11, f/16, f/22, or f/32.

Bokeh is pronounced BOH-Kə or BOH-kay. ... Bokehis defined as “the effect of a soft out-of-focus background that you get when shooting a subject, using a fast lens, at the widest aperture, such as f/2.8 or wider.” Simply put, bokeh is the pleasing or aesthetic quality of out-of-focus blur in a photograph.

particularly as it relates to film and photography, the optical phenomenon known as depth of field, is the distance about the plane of focus where objects appear acceptably sharp in an image.

Focal length is expressed in mm and a higher number means a bigger zoom, while a lower number mean the lens can be used for wider shots. As a rough reference, the human eye is said to see about the equivalent of 30-50 mm on a full frame camera (more on that later).

Shutter speed is a measurement of the time the shutter is open, shown in seconds or fractions of a second: 1 s, 1/2 s, 1/4 s … 1/250 s, 1/ 500 s, etc. ... In other words, the faster the shutter speed the easier it is to photograph the subject without blur and “freeze” motion and the smaller the effects of camera shake.

Camera shake is a term used to define the act of accidentally shaking a cameraduring shooting due to unsteady hands, which results in blurry images. This generally occurs more often if you're shooting on a low shutter speed or with a heavy lens, and can be avoided by using a tripod and cable release setup.

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.
