Engadget: Google used a 64-camera rig to train its portrait lighting AI

Engadget: Google used a 64-camera rig to train its portrait lighting AI. “Google’s Portrait Light feature can make some of your more mediocre photos look a lot better by giving you a way to change their lighting direction and intensity. The tech giant launched the AI-based lighting feature in September for the Pixel 4a 5G and Pixel 5 before giving older Pixel phones access to it. Now, Google has published a post on its AI blog explaining the technology behind Portrait Light, including how it trained its machine learning models.”
