AppleInsider:

Arguably one of the biggest differences in physical design for the 2018 iPhone models, the iPhone XR has only one rear camera while the iPhone XS and iPhone XS Max have two. AppleInsider takes a closer look at the situation to see if the iPhone XR’s single camera can still stand up to the dual-lens stablemates.

When the iPhone XR came out, I made the switch from the iPhone XS Max, thinking the camera would be just as good for those who want to save some cash, but I was wrong. After spending a month with the XR’s camera, I switched back to the XS Max. Here’s why.

Some very interesting photo evidence that starkly shows the differences. But the “average” user may not notice or care.
