Hands on with the iPhone 7 Plus’ crazy new Portrait mode

Well, I only judged by scaled down web photos, maybe it's the compression artifacts. But real bokeh seems to do something else than gaussian blur. For example,

> A small light source will be rendered as an aperture shaped figure with quite well defined edges in bokeh; but gaussian blur renders it as a spot with fading edges. In bokeh, noise is present at the same level as in in focus parts of image with same luminance; gaussian blur kills noise, so there'll be less noise than in non blurred parts of image. In bokeh, light areas will dominate over dark ones, while gaussian blur preserves the ratio of dark light areas.
