Lens

A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.

Aperture

In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical systemdetermine the cone angle of a bundle of rays that come to a focus in the image plane.

Camera

An electronic/analogic device used to take pictures, most cell phones nowadays include cameras, so its use it widespread. The tool of the trade!

3 Rules of Lighting

1. Light travels in straight lines.

2. A subject receives less light as the light source is moved farther away

3. The larger the light source relative to your subject, the softer the light.

Perspective

Perspective refers to the relationship of imaged objects in a photograph. This includes their relative positions and sizes and the space between them. In other words, perspective in the composition of a photograph is the way real three-dimensional objects are pictured in a photograph that has a two-dimensional plane. In photography, perspective is another illusion you use to produce photographs of quality composition. When you are making pictures, the camera always creates perspective.

Shutter

In photography, a shutter is a device that allows light to pass for a determined period of time, exposing photographic film or a light-sensitive electronic sensor to light in order to capture a permanent image of a scene.

Depth of field

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. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.

In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background.
