Basic Camera The Anatomy of a Camera
Seven Basic Parts of Any Camera Camera Body Lens Diaphragm Shutter / Shutter Release Film / Film Advance Focus Control Viewing System HOME
Camera Body • Is a light tight enclosure A simple light trap Differences between light tight & water tight • Prevents premature exposure of film • Provides a base structure to attach all accessories and/or control mechanisms. • The smaller the body the fewer the options HOME
Light Trap HOME
Light Trap • Light travels in straight lines • Some Light is absorbed when it hits a surface, while… • Some Light is reflected…. HOME
Light Trap Light Tight ≠ Water Tight • Water has the ability to flow or bend around corners Light Tight ≠ Water Tight HOME
LENS - Polished glass or plastic - “Collects” or “Gathers” light - Projects a reversed, upside down image on the film - Adjustable to provide a clear or focused image Several different styles available Some basic lens characteristics.. click on links below HOME

Diaphragm Light control device Controls the AMOUNT of light entering the camera - Usually made up of overlapping metal leaves - Adjustable to form openings of different sizes - APERTURE – Name of the hole formed by the diaphragm HOME
Shutter / Shutter Release Light control device Controls the TIME light is allowed to enter the camera A light proof shield between the lens & film Speed of opening/closing is adjustable Shutter Release – A means to trigger the opening Fast Shutter / Slow Shutter HOME

Film / Film Advance FILM A light sensitive material coated onto a base Discovery of a method for recording images created by light began photography as we know it. Lenses and various forms of image technology existed prior to the discovery/creation of film FILM ADVANCE Some type of system or device used to move exposed film out of the way and replace it with an unexposed piece. May be completely manual OR fully automatic. HOME
Film / Film Advance HOME
Focus Control A system that physically moves the lens in order to create a sharp image on the film Cameras with NO apparent focus control utilize the “Pinhole Principle” to obtain a focused image. HOME
Pinhole Principle We see reflected light in all directions A single ray of light can not be out of focus We can eliminate all but a single ray of light with an opening that is extremely small (a pinhole) resulting in a focused image HOME
Viewing System Method photographer uses to see approximate scene which will be captured on film May consist of one or more lenses Criteria under which all cameras are classified HOME
