Our phone cameras are getting better and better, and AI has been all the rage in photography lately. Google wants to bring AI lighting to your photos and help you relight your images after you’ve taken them. To train the algorithm, Google used an impressive rig with 64 cameras and 331 LED lights, and judging from the demos, the results are pretty awesome.
Researchers develop after-the-fact portrait relighting AI that works without 3D depth information
When the iPhone X came along with its Portrait Lighting effects, a lot of people were very impressed. Apple was even claiming that you don’t need studio lighting at all anymore or any other fancy equipment. You just need your phone. And while the iPhone hasn’t taken over as the portrait photographer’s camera of choice, it’s an intriguing concept.
A concept so intriguing that researchers and engineers at UC San Diego and Google have taken it a few steps further. They’ve trained neural networks to relight portraits after the fact without requiring any 3D depth data and with a lot more control than a few Apple presets.
