the distance measured from the optical center of the lens is set to focus at infinite position.

Characterized by the fact that it is thicker at the center and thinner at the side which is capable of bending the light together and forms the image inversely.

a medium or system which converge or diverge light rays passing through it to form an image

Inability of the lens to focus light that travels straight or lateral, thus making it blurred while the light reaching the lens oblique is the one the is transmitted sharp

It is considered as the smallest and the simplest type of camera

is that mechanism of a camera designed to control the degree of sharpness of the object to be photograph

a box designed to keep light out and serve as a frame to hold other parts

It is designed to control the time during which the light reaches the film

It is an inability of the lens to focus all colors in the same plane.

A device used in determining the Intensity of light that strikes the subjects and affects the filter

the inability of the lens to focus in both horizontal and vertical plane at the same time or the inability of the lens to focus on both lines running indifferent direction

a piece of colored glass, gelatin, plastic, or other material that attaches to of over the camera or enlarger lens to selectively absorb (or otherwise alter) the light passing through it

A stand consisting of three legs and a mounting head for a camera; Used to support and stabilize the camera

This is observed from the viewing system of the camera, once the object is not in focused the object will be viewed to be blurred and will turn sharp and clear once adjusted.

A lens which is partly corrected for chromatic aberration

is a lens with a focal length between 35mm to 50mm

Is that part of the camera which regulates the time exposure of the film thus, affecting the amount of light reaching the sensitized material.

A lens that has no correction

has a focal length longer than the diagonal of the film frame or image sensor.

A type of camera with dual lens. One for focusing and other for forming the image.

The ratio between the diameter and focal length of the lens; the light gathering power of the lens.

a lens defect wherein the photographic rays passing through the edges refract more sharply than those passing through the central part of the lens.

a tube inserted between the lens and camera body to provide increased magnification for macrophotography

used to filter out ultraviolet (UV) radiation, which can cause a bluish fog and loss of detail in distant objects;

In this type of focusing a single object will appear double once the object is not in focus, but moving the focusing adjustment this double image will coincide or superimposed to form a single object

focusing on the other hand will show an image in split or two parts once the object in not in focus once the two parts of the image has been united then the object is already focused.

Shutter speed of 60,125 and 300mm use?

lens corrected for distortion;

is photographic apparatus used to expose sensitized film or plates to reflected light images formed by a lens

the distance between the nearest and the farthest objects that are in acceptably sharp focus in an image captured with a camera.
