There's a few upgrades in the iPhone 7's camera that are worth digging into: while the resolution is the same, the improvements are more behind the scenes. You can look at things like a six lens system, but it's hard to demonstrate the practical benefits of these to the average user.

Instead, a few key upgrades stand out: much better low light performance, a faster shutter speed, brighter and more colorful images - complete with a better screen to view them on.

However, some of the changes don't add a huge amount, with some scenarios not showing a massive upgrade in picture quality.

Take a look at our side by side comparison shots and see for yourself the differences on offer. (iPhone 7 first, iPhone 6S second in each example):
