Photography - Basic Understanding

  1. 1. Photography7 October 2011Matic Golob
  2. 2. Index • What is photography? • Basic terms in photography • Equipment
  3. 3. Photography What is photography?
  4. 4. What is photography? The word photography comes from two ancient Greek words [1]: • Photo = "light“ "Drawing • graph = "drawing" = with light" “Today, photography has become a powerful means of communication and a mode of visual expression that touches human life in many ways.” [1]
  5. 5. PhotographyBasic terms in photographyAnd what they mean
  6. 6. Basic terms inphotographyand what they mean • Exposure • Shutter speed • Aperture • ISO • Understanding those terms is crucial if you want your photography will look like ones in magazines.
  7. 7. Exposure • “A good exposure occurs when you maintain as much detail as possible in both the very bright parts (highlights) as well as the very dark parts (shadows) of an image” [2]. Bad exposure Good exposure
  8. 8. Shutter speed • Shutter speed is a time which tells us for how much time the shutter will be open. • It is measured in seconds. • D-SLR cameras usually supports times between 30s and 1/8000s.
  9. 9. Shutter speed Fast shutter speed • Shorter times are used to stop motions and freeze the subjects. • For sport, macro, nature and every day photography.
  10. 10. Shutter speed Long exposure • Longer times are used for isolating objects or pointing them out. • Used to achieve dramatic effects. • Used mostly in waterscape and architecture photography.
  11. 11. Aperture • Aperture is a hole which light is admitted. • Aperture also controls depth of field (DOF), which refers to how much of the image is in focus.
  12. 12. Aperture “Inside the camera lens is a system of blades which open and close to increase or decrease the opening through which light passes into the camera.” [2]
  13. 13. ISO • ISO value tells us the sensor sensitivity to the light • High ISO means high sensor sensitivity and opposite • ISO value effect to photo quality • Higher ISO means lower quality (more noise)
  14. 14. PhotographyEquipment
  15. 15. Equipment • Cameras • D-SLR Cameras • Compact Cameras (pocket cameras) • Lenses • Standard lenses • Telephoto lenses • Zoom lenses • Wide Angle lenses • Speedlights (Flashes) - Adam Buhler
  16. 16. D-SLR Cameras • Digital Single Lens Reflex Cameras • Advantages: [3] • You can see exactly what the lens sees • The lenses are exchangeable • Larger image sensors (high-quality photos) • D-SLR cameras are very fast cameras and has a near-zero lag time
  17. 17. Lenses • Standard lenses (KIT lenses) • Provided by a manufactures along with the cameras. • Generally, these lenses have focal length somewhere between 17mm and 70mm. • Telephoto lenses • These are the lenses with longer focal length. • Normally between 70mm and 500mm. • They have fixed focal length.
  18. 18. Lenses • Zoom lenses • These are the lenses with variable focal length. • The most standard Focal length are 18-55mm, 70-200mm and 70-300mm. • These lenses are very common. • Wide Angle lenses • These are the lenses with low focal length (between 10mm to 24mm). • They are mostly used for landscape photography.
  19. 19. Speedlights (Flashes) • Integrated Speedlights • Built-in cameras • External Speedlights • Mostly for D-SLR cameras • Provide much more light • They are programmable • Studio Flashes • Used for commercial photography
