Look how much the iPhone camera has improved over time

Business InsiderThe iPhone 6's camera.Apple's first iPhone went on sale eight years ago today.

The iPhone has evolved a lot since then - the original iPhone wasn't just thicker and heavier than the phones we use today, its components were also much more limited.

This is especially evident when you look back on photo samples from the original iPhone compared to those of today.

The original iPhone had a 2-megapixel camera that couldn't even record video. To put that in perspective, the iPhone 6 has an 8-megapixel camera that comes with a few fun video editing features, such as the ability to record video in slow motion.

Lisa Bettany, cofounder of apps Camera+ and MagiCam, has taken a series of photos with every single iPhone to see just how drastically the image quality has changed. She gave us permission to rerun her photos.

Flipping through them is a great reminder of how far we've come in a short time.
