Transcript of "13 Slr"

  1. 1. Single-lens Reflex Camera
  2. 2. SLR Camera <ul><li>camera that uses a semi-automatic moving mirror system which permits the photographer to sometimes see exactly what will be captured by the film or digital imaging system </li></ul><ul><li>cameras allow the photographer to see the precise focus, color, framing, and brightness that will be recorded on film </li></ul>
  3. 3. Optical components of an SLR camera 1 - Front-mount lens 2 - Reflex mirror at 45degrees 3 - Focal plane shutter 4 - Film or sensor 5 - Focusing screen 6 - Condenser lens 7 - Optical glass pentaprism 8 - Eyepiece
  4. 4. History <ul><li>18 th Century </li></ul><ul><li>Johann Sturm (Germany) described first known use of a reflex mirror in a camera obscura. </li></ul><ul><li>The camera obscura was known to Aristotle as an aid in observing solar eclipses, but its use as an artist's aid </li></ul>
  5. 5. History <ul><li>19 th Century </li></ul><ul><li>Used glass plates or sheet film </li></ul><ul><li>first focal-plane shutter SLR </li></ul>
  6. 6. History <ul><li>Early 20th century </li></ul><ul><li>first production 35 mm </li></ul><ul><li>first medium format roll film SLR </li></ul><ul><li>first pentaprism eyelevel viewing 35 mm SLR </li></ul>
  7. 7. Further Development of SLR <ul><li>Large format SLR </li></ul><ul><li>describes large photographic films, large cameras, view cameras and processes that use a film or digital sensor, generally 4 x 5 inches or larger. </li></ul><ul><li>have adjustable fronts and backs that allow the photographer to better control rendering of perspective and depth of field. </li></ul>
  8. 8. Large format SLR <ul><li>allow the front and/or back of the camera to be tilted out of parallel with each other, and to be shifted up, down, or sideways. </li></ul>
  9. 9. Medium format SLR <ul><li>cameras making use of sensors larger than that of a 35 mm film frame </li></ul><ul><li>most widely used film size to a niche used by many professionals and some amateur enthusiasts </li></ul>
  10. 10. Medium format SLR <ul><li>images of much higher resolution can be produced </li></ul><ul><li>usually limited to professional photography shops and very expensive </li></ul>
  11. 11. Advantages <ul><li>viewing and focusing the image through the attached lens </li></ul><ul><li>provide photographers with precision and confidence </li></ul><ul><li>no parallax error, and exact focus can be confirmed by eye </li></ul><ul><li>very versatile </li></ul>
  12. 12. Disadvantages <ul><li>cannot be made as small or as light as other camera designs </li></ul><ul><li>simple designs for wide angle lenses cannot be used </li></ul><ul><li>SLR mirror 'blacks-out' the viewfinder image during the exposure </li></ul>
