Functions:

The camera, the image-forming device, is a sensing medium. The recording medium in a camera can be the film itself, or a digital electronic or magnetic memory.

Photographers control the camera and lens to "expose" the light recording material (such as film) to the required amount of light to form a "latent image" (on film) or "raw file" (in digital cameras) which, after appropriate processing, is converted to a usable image. Digital cameras replace film with an electronic image sensor based on light-sensitive electronics such as charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) technology. The resulting digital image is stored electronically, but can be reproduced on paper or film.

The movie camera is a type of photographic camera which takes a rapid sequence of photographs on strips of film. In contrast to a still camera, which captures a single snapshot at a time, the movie camera takes a series of images called a "frame". This is accomplished through an intermittent mechanism. The frames are later played back in a movie projector at a specific speed, called the "frame rate" (number of frames per second). While viewing, a person's eyes and brain merge the separate pictures together to create the illusion of motion.

There are few controls to ensure the photograph is clear, sharp and well illuminated. The controls usually include the following (which would later be on discussed):
1. Focus
2. Aperture
3. Shutter sped
4. White Balance
5. Metering
6. ISO Speed
7. Auto-focus point

Many other elements of the imaging device itself may have a pronounced effect on the quality and/or aesthetic effect of a given photograph; among them are:

• Focal length and type of lens (telephoto or "long" lens, macro, wide angle, 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.

• The nature of the light recording material, for example its resolution as measured in pixels or grains of silver halide.
