1. ISO & Shutter Speed

2. Shutter Speed:
Shutter speed is the duration of time the shutter remains open to allow light to reach a digital camera sensor. Shutter speed is measured in seconds, or fractions of seconds.
Using very fast shutter speeds “freeze” fast-moving subjects
Slow shutter speeds are used to intentionally capture the movement of a subject
For most, hand holding a digital camera at shutter speeds below 1/60th of a second often require use of a camera support to prevent camera shake.

7. ISO:
ISO is the number indicating a digital-camera-sensors sensitivity to light.
The higher the sensitivity, the less light is needed to make an exposure.
Shooting at a lower ISO number requires more light than shooting at a higher number.
Lower numbers result in images with the least visible noise, which is desirable. The higher the number, the more noise.

ISO exercise 1: you will be required to shoot a subject using the lowest ISO setting to the highest. Determine the right exposure (shutter speed & ISO 100) and then increase the ISO setting to 200, 400, and so on.
ISO exercise 2: Determine your exposure (shutter speed & ISO 100) but this time adjust the Shutter & Aperture to maintain the correct exposure as you increase the speed of the ISO.

Shutter exercise1: Keep the fan speed at 1 and capture images using shutter settings from 1/4th of a second till 1/1000th of a second. Repeat this exercise after changing the fan speed from 1 to 2 and the from 2 to 3 and so on.
