Assignment 2.2 Shutter Speed, 2.3 ISO
Lecturer:
Shutter Speed- The DURATION of time the shutter remains open to allow light to reach a digital camera sensor.
- Measured in seconds or fractions of seconds.
- Using very fast shutter speed 'freezes' fast moving subjects.- Slow shutter speeds are used to intentionally capture the movement of a subject.
- Holding a digital camera at shutter speeds below 1/60th of a second often requires use of a camera support to prevent camera shake.
- Standard shutter speed stops are 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, 1/4, 1/2, 1, 2, 4, 8

ISO- The number indicating a digital camera's SENSITIVITY to light.
- The higher the sensitivity, the less light is needed to make an exposure.
- Shooting at lower ISO number requires more light than a higher ISO number.- Lower number results in images with the least visible noise, which is desirable. The higher the ISO number, the more noisy the images will be.
- Standard ISO stops : 50, 100, 200, 400, 800, 1600, 3200, 6400

Instructions for Exercise 2.2 Shutter Speed :-
Shutter Speed (5%)
Marking Criteria: The student must capture the evidence of the Shutter’s ability to freeze fast moving objects and blur moving objects.
Exercise 2.2
Keep the fan speed at 1 and capture images using shutter settings from 1" of a second till 1/1000th of a second. Repeat the exercise after changing the fan speed from 1 to 2 to 3 and so on.

Instructions - Exercise 2.3 ISO
ISO (5%)
Marking Criteria: The student must capture the evidence of degradation of image as the ISO increases in sensitivity. The student also must produce evidence that ISO can directly affect exposure.
Exercise 2.3a
You will be required to shoot a subject using the lowest ISO setting to the highest. Determine the right exposure (shutter speed, aperture at ISO 200) and then increase the ISO setting to 200, 400 and so on.
My reluctant subject matter is Minion.
Shutter speed: 1/15, Aperture: 5.6, ISO: 200
Shutter speed: 1/15, Aperture: 5.6, ISO: 400
Shutter speed: 1/15, Aperture: 5.6, ISO: 600
Shutter speed: 1/15, Aperture: 5.6, ISO: 1200
Determine your exposure (shutter speed and aperture at ISO 200) but this time adjust the shutter speed and aperture to maintain the correct exposure as you increase the ISO.
Shutter speed: 1/15, Aperture: 5.6, ISO: 200
Shutter speed: 1/25, Aperture: 5.6, ISO: 400
Shutter speed: 1/50, Aperture: 5.6, ISO: 600
Shutter speed: 1/100, Aperture: 5.6, ISO: 1200
