ISO, Aperture and Shutter Speed For Beginners Slide 2 The photographer can control how much natural light reaches the sensor by adjusting the camera's ISO shutter speed and aperture Slide 3 ISO With digital cameras, the ISO indicates how quickly the sensor absorbs light As the ISO increases, so does grain or noise ISOConditions 100 or 200Outside, sunny conditions 400 to 800Night time low light 1600Dark scenes Slide 4 ISO 100 - bright sunlight 1600 - low light Slide 5 Shutter Speed (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 ) Slide 6 Shutter Speed (Tv) Slow Shutter speed for blurring water 10 seconds Fast Shutter speed freezes the action 1/200 th second Slide 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 Slide 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 Slide 9 Aperture Av = 16 Av = 1.4 Slide 10 How to take better images using these 3 features 1.Action Fast shutter speed to freeze the motion Slide 11 2. Portrait This setting uses a wide aperture (1.4 - 3.5) to make the background out of focus Slide 12 3. Landscape This setting uses a small aperture (16) to have most objects in focus Slide 13 4. Night Shots High ISO to increase the amount of light being absorbed by the sensor Slide 14 5. Low Light High ISO and no flash Eg 1600 ISO. Slide 15 Special Effects Long Exposures8 seconds, ISO 100, F2.8, flash
