Meet Kevin Systrom and Piper Hanson as they explain how digital images work.

What are pixels, those tiny dots of light, made from? How are colours created and represented? What does Kevin say about the way mathematical functions are used to create different image filters? What is the difference between image resolution and density?

As Kevin says at the beginning of this clip, you need to know what problem you're solving when you start to think about designing and developing an app or an idea. Think about a problem you'd like to solve for people and start figuring out what the solution might look like!
