Taking pictures of a scene with a a large number of stops of light or large dynamic range (very bright and very dark areas)
requires to choose between the two exposures (light versus dark)
Cameras only have the ability to capture 6 - 8 stops of light (your picture was about 12 stops is my guess)
Choosing the darker area is usually preferable as people prefer to see detail in the shadows
There is an HDR (High Dynamic Range) app for the iPhone that compresses the range down to 6 or 7 stops of light which is what a screen or printer can display.
Does the iPhone camera use a spot meter?
