Focal Length and Angle of view. The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters.

# data[].attributes.body
In optics, particularly as it relates to film and photography, depth of field (DOF), also called focus range or effective focus range, is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.

# data[].attributes.body
A digital single-lens reflex camera (also called a digital SLR or DSLR) 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.

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
The "program" in Program mode 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.

# 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
Shutter priority refers to a setting on some cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure.

# data[].attributes.body
Automatic mode 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 aperture setting 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
he 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.

Auto focus 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

# data[].attributes.body
Bracketing is the process of taking three photos; one using the camera's recommended settings, one intentionally underexposed, and one intentionally overexposed. The reason is simply to be sure you can get a good exposure from a subject that's hard to meter.

# data[].attributes.body
An electronic viewfinder 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.

# data[].attributes.body
A light meter is a 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
A point-and-shoot camera, also known as compact camera, is a still camera designed primarily for simple operation. Most use focus free lenses or auto focus for focusing, automatic systems for setting the exposure options, and have flash units built in. ... None have lens threads.

In photography, 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
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 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.

# data[].attributes.body
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
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.

# 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.

# data[].attributes.body
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.

# 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.

The term post-processing is used in the video/film business for quality-improvement image processing methods used in video playback devices, and video players software and transcoding software.

# data[].attributes.body
Long-exposure, 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
Camera resolution is measured in megapixels; both image ﬁle resolution and monitor resolution are measured in either pixels per inch or pixel dimensions and printer resolution is measured in dots per inch.

The mid tones are indirect light that is illuminating an object. Now that this has been established, the next thing is to begin drawing. Before that though, we need to understand where the highlights mid tones, and shadows are. This can be difficult when looking at an object in color.

# data[].attributes.body
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.

# data[].attributes.body
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.
