A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies. The camera is a remote sensing device as it senses subjects without any contact . The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface.
Important part of a camera:
Focal - length and type of lens (normal, long focus, wide angle, telephoto, macro, fisheye, or zoom)
Filters - placed between the subject and the light recording material, either in front of or behind the lens
Inherent - sensitivity of the medium to light intensity and color/wavelengths.
