ISO measures sensitivity to light.
In this tutorial you will learn:
- A low ISO values means that the sensor is less sensitive to light.
- Using a lower ISO produces clearer, smoother images.
- Using a higher ISO can result in grainier, 'noisier' images.
- Avoid high ISO values except in low light situations, when a long exposure isn’t possible.
- As a rule of thumb, an ISO of less that 800 will produce clear images.
