Google trained its AI camera with help from pro photographers

"We ended up discovering--through trial and error and a healthy dose of luck--a treasure trove of expertise in the form of a documentary filmmaker, a photojournalist, and a fine arts photographer," said Josh Lovejoy, Senior Interaction Designer at Google. "Together, we began gathering footage from people on the team and trying to answer the question, 'What makes a memorable moment?'" Some of that learning comes down to principles that you may have learnt as you've struggled to get to grips with a new smartphone camera or point-and-shoot. Understanding focus, particularly depth of field, and the rule of thirds are key, but so are some more "common sense" suggestions. Everybody knows to keep fingers out of the shot and to not make quick movements, but machine learning algorithms have no such understanding.
