What is ISO?

Editor’s Tip: Have you ever wondered what the ISO function on your camera does? The ISO is your camera’s sensitivity to light. The greater the number, the less light you will need to take a picture. So, if your photo is coming out too dark, try increasing the ISO. Just be careful that the ISO isn’t too high, because it can result in an image with a lot of noise.

This example shows how a high ISO can cause noise in a photo. Luckily you can help fix it by uploading it to Krome Photos or using a photo editing program.
