On a bright and sunny day there is a lot of light so you can use a lower ISO setting. On a cloudy day there is less light, so you must increase your ISO. But, there is a trade off. As ISO numbers go up, so does the noise in your photos.

Here is the proof:. Look at the difference between 80 and ISO in these photos. Notice how much smoother the 80 ISO photo looks. The ISO photo shows lots of noise. You can really notice it in the darker areas. The camera I used in those photos was an older model Canon point and shoot. Noise appears in images as random colored pixels, especially in darker areas of an image such as night skies. This is caused by random fluctuations in electrical signals passing through the sensor.

When a lot of light is available these random fluctuations are overpowered by the available light. In low light situations, where the ISO setting has been increased, the captured light energy is similar in electrical terms to the fluctuating electrical signals already present on the sensor. The camera then amplifies the brightness of all pixels — including those which have been randomly affected by electrical signals.

This is why the grain or noise becomes so noticeable. Many of the people are chatting very quietly. Light is represented by our guest speaker talking without a microphone. If he talks too quietly for us to hear him too little light then we need to amplify the recording use a higher ISO value. To recap:. By now you should be comfortable to take control of ISO when you need to.

What Is ISO? What Is Exposure? You can vary the ISO whenever you want, inbetween every shot if you like! Your camera will automatically select a suitable ISO value in Auto modes. In semi-automatic modes and manual mode you can take control of the ISO yourself. In these situations, increase your ISO value until you get the correct exposure.
