In WWDC 2018 session 503, the new Portrait Matte feature is discussed. In the first few minutes of the session, it is mentioned that both TrueDepth and DualCamera devices are supported, and it is stipulated that "people" must be in the frame.
I don't have access to a device with a DualCamera module + iOS 12 beta so I can't just try this out... my question is: on a DualCamera device (ie. iPhone 8 Plus rear camera), is it possible to receive a portrait matte that shows more than one human subject? For example, if four people are standing against a wall, will the portait matte recognize all of them?
Borrowed an iPhone 8 Plus.
Yes, portraitEffectsMatte can indeed handle more than one person in a frame!
I tried with up to 4 people, at various depths (together, apart, some/none/lots of lateral distance), and it worked much better than I expected (almost always "caught" all 4 people in the matte).
GREAT job Apple.
