Profoto TTL for iPhone Shows Us Just How Limited Apple ProRAW Is

Recently, Profoto updated their iPhone app. The Profoto app has a camera built-in that lets you use flashes like the B10 as a strobe. Except instead of shooting with a real, dedicated camera, you're using your iPhone. The recent update includes TTL algorithm changes. We spoke with Profoto's product manager and tested it out for ourselves. It's a stark reminder of just how limited a camera phone's sensor still is.
