• Cameras may job with the lambent of the visible spectrum or with other portions of the electromagnetic spectrum

• A camera generally consists of an enclosed hollow with an opening (aperture) at one prong for light to enter, and a recording or viewing surface for capturing the glassy at the other end
• A majority of cameras have a lens positioned in anterior of the camera's opening to gather the incoming light and focus all or constituent of the image on Site the recording surface
• The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed-size aperture.

The first colour photograph was made by James Clerk Maxwell, with the help of Thomas Sutton, in 1861
