Deep Fusion photography

The iPhone 11’s Deep Fusion camera is now in the iOS 13 developer beta

Apple launched an early look at its new Deep Fusion feature on iOS yesterday with a software update for beta users. The technique uses machine learning to create highly detailed, sharper and more natural-looking photos on the primary and telephoto lenses by combining the results of multiple shots. According to Apple, Deep Fusion requires the A13 and will not be available on any older iPhones.

With Deep Fusion, the iPhone 11 and 11 Pro cameras will have three modes of operation that automatically kick in based on light levels and the lens you’re using:

The standard wide angle lens will use Apple’s enhanced Smart HDR for bright to medium-light scenes, with Deep Fusion kicking in for medium to low light, and Night mode coming on for dark scenes.
The tele lens will mostly use Deep Fusion, with Smart HDR only taking over for very bright scenes, and Night mode for very dark scenes.
The ultrawide will always use Smart HDR, as it does not support either Deep Fusion or Night mode.
