TrueDepth vs. back camera: Which iPhone X portrait mode is better?Which portrait mode reigns supreme: TrueDepth's sensors or the rear camera's dual-lens system?
When I first had a chance to play with the iPhone X's TrueDepth front-facing camera system during the last iPhone event, I left Steve Jobs Theater with cameras on the brain.
True Depth vs. Dual Lens
Thanks to physics, it's highly unlikely we'll ever see true shallow depth of field on an iPhone — there's just not enough room in the casing for a proper lens. But Apple (and its competitors) have been hard at work building effective simulations for various "bokeh" depth of field effects.
On the iPhone X, Apple has implemented it in two distinct ways: On the front of the iPhone X, the TrueDepth's various IR and dot sensors help measure depth, while the dual-lens rear camera system estimates depth by using the varied focal length of the two lenses.
Both techniques make up Apple's "Portrait mode," but they're using very different technology to achieve the same result. When you use ...
