  1. ISO, Aperture and Shutter Speed For Beginners

  2. The photographer can control how much natural light reaches the sensor by adjusting the camera's • ISO • shutter speed and • aperture

  3. ISO • With digital cameras, the ISO indicates how quickly the sensor absorbs light • As the ISO increases, so does grain or noise

  4. ISO 100 - bright sunlight 1600 - low light

  5. ShutterSpeed (Tv) • You can control the length of time the shutter remains open by setting the SHUTTER SPEED. Longer shutter speeds = more light (1/4 second or less)shorter shutter speeds = less light (1/250 second or more )

  6. ShutterSpeed (Tv) Slow Shutter speed for blurring water– 10 seconds Fast Shutter speedfreezes the action – 1/200th second

  7. Aperture (Av) • Before light reaches the sensor, it must pass through an opening called an "Aperture • Similar to your pupil which closes down in bright conditions and opens wider in darker conditions

  8. Aperture Wide aperture = small number = more light Also less depth of field or area in sharp focus Small aperture = large number = less light More depth of field or area in sharp focus

  9. Aperture Av = 16 Av = 1.4

  10. How to take better images using these 3 features • Action Fast shutter speed to freeze the motion

  11. 2. Portrait This setting uses a wide aperture (1.4 - 3.5) to make the background out of focus

  12. 3. Landscape This setting uses a small aperture (16) to have most objects in focus

  13. 4. Night Shots • High ISO to increase the amount of light being absorbed by the sensor

  14. 5. Low Light • High ISO and no flashEg 1600 ISO.

  15. Special Effects • Long Exposures–8 seconds, ISO 100, F2.8, flash
