• Camera.
• 135mm, 120mm.
• Single Lens Reflex (SLR).
• Twin Lens Reflex (TLR).
• Lens.
• Zoom, wide angle, telephoto, fish-eye.
• Filters.
• Softener, star, color.

5
Photographic Equipment

• Flash.
• Tripod.
• Monopod.

6
Components of a camera

• Camera.

7
Key functions and concepts

• Aperture.
• An opening that controls the amount of light goes
  into the camera by varying the size.
• It controls the range of distance that is sharp
  in focus (depth of field).
• F-stops - F16, F11, F8, F5.6, F4, F2.8.
• The larger the F-stops number, the smaller the
  opening, the longer the depth of field.

8
Key functions and concepts

• Shutter speed.
• By varying the speed, it controls the amount of
  time the light enters the aperture and reaches
  the film.
• Speed - 125, 60, 30, 15, 8, 4, 2, 1, 2(125
  means 1/125 second).
• The longer the exposure time, the brighter the
  photo.

9
Key functions and concepts

• Film speed.
• Determines the sensitivity of the film for the
  exposure to light.
• ISO - 800, 400, 200, 100, 25.
• The higher the film speed, the shorter the time
  needed to make a normal exposure, the larger the
  grains on the photo.
