Our camera shootout between the new iPhone 8 and the two-year-old iPhone 6s reveals you don't really need to upgrade

Whenever a new iPhone comes out, my first thought is, "Should I upgrade for the camera?"

While I weigh other concerns when upgrading - mainly price and how my old phone is holding up - the most enticing feature of any new phone for me is a camera. 

I've been using an iPhone 6s for the past six months or so. It's a great phone, and I've never had any problems with it. And since I had upgraded from an iPhone 5s, and I could easily see a difference in the quality of my photos.

But when the iPhone 8 came out, I wondered if it would be a major upgrade from my current phone - after all, the iPhone 6s is now two years old. 

I decided to spend a few weeks photographing my life with both phones, side-by-side, to decide which camera I like better, then selected a handful of shots that showcased the cameras' differences.
