Does anyone here have insight as to the differences between the various versions of Apple's "Smart HDR" feature? Interesting to see it took the leap from Smart HDR3 (previous model) to Smart HDR 4 (new model), and yet the latest iPhones released last month apparently use Smart HDR 5.
The version is tied to the Image Signal Processor (ISP) of the A-series chip. So the A17 has Smart HDR 4, while the A18 has Smart HDR 5.
Smart HDR uses neural image segmentation for tone mapping and other processing. In my opinion it goes way too far; trying to grab a faintly blue sky and make it as blue as possible, identifying a face and lightening any hint of a shadow, etc.
When people complain about iPhone photos looking over processed, this is why.
Smart HDR 5 but Auto WB is still stuck in kindergarten. Priorities I guess.
