The Camera

Electromagnetic Spectrum: The range of wavelengths or frequencies over which electromagnetic radiation extends.


Camera obscure: A darkened box with a convex lens or aperture for projecting the image of an external object onto a screen inside.


Image Sensor: An image sensor is a device that converts an optical image to an electric signal.

Photographic film: photographic material consisting of a base of celluloid covered with a photographic emulsion



   

Aperture: A space through which light passes in an optical or photographic instrument, esp. the variable opening by which light enters a camera.

Shutter: A shutter is a device that allows light to pass for a determined period of time.

Exposure: The state of being exposed to contact with something.

Depth of field: The distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.

F-stop: In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system

Focal length: The distance between the center of a lens or curved mirror and its focus
