Using the whole frame for determining the correct exposure is not always desirable. What if you are trying to take a headshot of a person with the sun behind? This is where center-weighted metering comes in handy. Center-weighted Metering evaluates the light in the middle of the frame and its surroundings and ignores the corners. Compared to Matrix Metering, Center-weighted Metering does not look at the focus point you select and only evaluates the middle area of the image.

# data[].attributes.body
Spot Metering only evaluates the light around your focus point and ignores everything else. It evaluates a single zone/cell and calculates exposure based on that single area, nothing else. I personally use this mode a lot for my bird photography, because the birds mostly occupy a small area of the frame and I need to make sure that I expose them properly, whether the background is bright or dark. Because the light is evaluated where I place my focus point, I could get an accurate exposure on the bird even when the bird is in the corner of the frame. Also, if you were taking a picture of a person with the sun behind but they occupied a small part of the frame, it is best to use the spot metering mode instead. When your subjects do not take much of the space, using Matrix or Center-weighted metering modes would most likely result in a silhouette, if the subject was back-lit. Spot metering works great for back-lit subjects like that.

Metering is the brains behind how your camera determines the shutter speed and aperture, based on lighting conditions and ISO speed. Metering options often include partial, evaluative zone or matrix, centre-weighted and spot metering.

A candid photograph is a photograph captured without creating a posed appearance. This is achieved in many ways, for example: when the subject is in motion, by avoiding prior preparation of the subject, by surprising the subject, by not distracting the subject during the process of taking photos

Freezing. Freezing is a very common technique. Given a scene with an object that moves at a certain speed, the photographer can capture it with a high shutter speed and freeze the action. ... ISO – ISO can be raised in order to achieve fast enough shutter speed.

The Bulb setting on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button

Continuous Focusing Mode. AI Servo AF (Canon)/AF-C (Nikon) stands for Continuous Focus and this mode is most useful for keeping moving objects sharp within the viewfinder as you track the object. As soon as you begin to depress the shutter release, the camera goes into action and begins to focus

In the field of photography, a manual focus camera is one in which the user has to adjust the focus of the lens by hand. Before the advent of autofocus, all cameras had manually adjusted focusing; thus, the term is a retronym

is a photographic technique - moving light object (like candle, flashlight, burning stick etc) in front of camera, whilst taking a long exposure photograph

# data[].attributes.body
Light painting, painting with light, light drawing, or light art performance photography are terms that describe photographic techniques of moving a light source while taking a long exposure photograph, either to illuminate a subject or space, or to shine light at the camera to 'draw', or by moving the camera itself

Digital single Lens reflex, adapt lenses greater control over exposing settings, can shoot in he RAW format, which gives total control over the editing.

a 'stop' is a measurement of an exposure, depending on either the shutter speed, the ISO or the aperture. To be specific, if you were to increase the exposure by one stop, you would be doubling the exposure. So, for example, your aperture is f/4, shutter speed is 1/100 and ISO is 100

A paper  coated with a light-sensitive chemical formula, used for making photographic prints. ... A range of emulsions are also available that differ in their light sensitivity, colour response and the warmth of the final image.

A pinhole camera is a simple camera without a lens but with a tiny aperture, a pinhole – effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect

composition is the placement or arrangement of visual elements or 'ingredients' in a work of art, as distinct from the subject. The term composition means 'putting together' and can apply to any work of art, from music to writing to photography, that is arranged using conscious thought.

ISO in Digital photography. 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.

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.

Framing refers to using elements of a scene to create a frame within your frame. For example, you might shoot through a doorway, pulled back curtains, branches, fences, tunnels, or arches to highlight your subject.

Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film.

resolution is the detail an image 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. ... Photographic lens and film resolution are most often quoted in line pairs per millimetre.

Refraction is the bending of light as it passes from one substance to another. Here, the light ray passes from air to glass and back to air. The bending is caused by the differences in density between the two substances.

Lighting  is the illumination of scenes to be photographed. A photograph simply records patterns of light, colour, and shade; lighting is all-important in controlling the image. In many cases even illumination is desired to give an accurate rendition of the scene.
