See a great comparison here:
You can slide between shots from both cameras and compare them side by side. (Make sure you move the slider in the middle of the photos.)
I’m surprised by how consistently different the colours in the photos are. The iPhone photos look ‘nicer’ but they also look less realistic. It’s hard to know which is more realistic without seeing the original scene. The colours and saturation on the iPhone seem a little too enhanced to me. What do other people think?
