  1. Cameras(with a “C” not Kameras)

  2. Cameras are defined by • Size (film or sensor) • Format (film or sensor) • Viewing system • Focusing systems • Special use

  3. Camera Size & Format • Typical Film/Sensor sizes • Miniature • APS (Advanced Photo System) Server beginning at 24mm • 35mm - 24x35mm • Digital – varies by size and proportion • Medium Format - 2 ¼ x X, • (2 ½ x 1 5/8 up to 2 ¼ x 3 ¾) • Large Format • 4x5, 5x7, 8x10, 11x14 & Panorama

  4. Camera Viewing & Focusing • View Finder • Pre, manual & auto focused • Split image • SLR • View through the taking lens • Manual focus or Auto Focus • Ground Glass • Medium and large format

  5. Camera Shutters • Leaf shutter • quiet, reliable, exposes entire frame at one time • limited to 1/400 sec • In lenses, difficult to interchange lenses • Focal plane shutter • fast, over 1/4000 sec • In camera body, east to interchange lenses • Exposes part of frame at a time

  8. Rangefinder - pros • View through a viewing window • Simple to sophisticated • Good in low light levels • Usually has built-in light meter • Miniature to “field camera” size • Usually has leaf shutter • Focal plane shutters more expensive • Rugged & quiet

  9. Rangefinder - cons • Has a “parallax” problem - you do not see what you will get • Inter-changable lenses tend to be more expensive

  10. Single Lens Reflex • View through taking lens - you see what you will get • Typically 35mm & medium format • Some medium formats have interchangable backs. • Interchangeable lenses inexpensive

  11. Usually has built-in light meter • Usually uses focal plane shutter • Some medium formats use leaf shutters • Tend to be noisy

  12. Twin Lens Reflex • Medium format • Rugged • Leaf shutter • Parallax • Few made today • Digital version ? • Few lenses

  13. Twin Lens Reflex Image reversed left-to-right

  14. View Camera • Large format • Requires a tripod • Very flexible • Slow to setup and use

  15. Swings and tilts, rise and fall

  16. Field Camera • Large format, usually 4x5 • Made to be hand-held • May or may not have swings and tilts • Rangefinder or ground glass focusing
