Studio lighting mode.
After the test run the other day my son opted for the Studio Light portrait mode in the iPhone 11 Pro, donned a favorite shirt, combed his hair and voila! The shade of the orange tree makes for soft, diffuse lighting on what was a very sunny day. We only get 350 of those a year in Scottsdale.

iPhone 11 Pro snap, SOOC. The Portrait mode automatically blurs the background and the degree of blur can be changed in post processing.
