When using many of the automatic cameras today, many of the features listed below are obsolete. This list is provided for those students who are enthusiasts of the manual camera.
Lens - It draws the light into the camera and focuses it on the film plane.
Shutter - It open and closes to control the length of time light strikes the film. There are two types of shutters: a leaf shutter, located between or just behind the lens elements, and a focal plane shutter, located in front of the film plane.
Shutter Release - The button that releases or "trips" the shutter mechanism.
Film Advance Lever or Knob - It transports the film from one frame to the next on the roll of film.
Aperture - It dilates and contracts to control the diameter of the hole that the light passes though, to let in more or less light. It is controlled by the f-stop ring.
Viewfinder - The "window" through which you look to frame your picture.
Film Rewind KnobThis knob rewinds the film back into the film cassette.
Camera Body - The casing of the camera which holds the encloses the camera pats.
Flash Shoe - This is the point at which the flash or flash cube is mounted or attached.
Self-Timer - This mechanism trips the shutter after a short delay - usually 7 to 10 seconds - allowing everyone to be in the photograph.
Shutter Speed Control - This know controls the length of time the shutter remains open. Typical shutter speeds are measured in fractions of a second, such as: 1/30 1/60 1/125 1/250 1/500 and 1/1000 of a second.

A darkroom is a workspace, usually a separate area in a building or a vehicle, made dark to allow photographers to use light-sensitive materials to develop film and photographic paper to make photographic prints. Darkrooms have been in use since the late 19th century for black and white photography. Using black and white film, photographers could control every step of the photographic process.
The darkroom does not have to be completely dark when making black and white prints. Most black and white print papers are only sensitive to blue light, or to blue and green light, so black and white darkrooms feature a specially-made red or amber coloured light, known as a safelight. It enables the photographer to work in the light so they can see what they are doing, without exposing the paper. A low-intensity orange or yellow light can also be used, but these are less common than the red safelight. Colour print paper, on the other hand, is sensitive to all parts of the visible spectrum and therefore must be kept in complete darkness until the prints are properly fixed. There is however a very dim amber safelight that can be used in colour photography, but it is so dim as to be of little use. For both colour or black and white paper, a "paper-safe" -- a light-proof box to safely store photographic paper not in use as opposed to the boxes and light-proof bags that the paper comes packaged in -- can be used.
Another use for a darkroom is to load film in and out of cameras, development spools, or film holders, which requires complete darkness. Lacking a darkroom, a photographer can make use of a changing bag, which is a small bag with sleeved arm holes specially designed to be completely light proof and used to prepare film prior to exposure or developing.
