I recently got an iPhone 13 Pro. I love it. For me, the thing that sticks out most - literally - is the camera. 

For a long time, iPhones have had increasingly better cameras. The last few generations, camera performance has headlined the marketing messaging: Get the new iPhone, because the camera is a lot better. It is one of the few things that gets people to upgrade. 

And indeed, the 13 Pro's camera takes really good pictures. But it is not just the iPhone. Virtually all of today’s top smartphones can take images on par with anything you can get with a standalone. 

How does your mobile phone camera work? And how did it get to be so good? In this video we will look at the amazing computer and semiconductor engineering that goes inside this impressive feature.
