> Does the human eye have bokeh? Yes. When your eye is focused on something close, point sources of light in the background will look larger and blurry. You'll also see two of them if you have two eyes open and have a sense of depth that a single lens projecting the scene onto a flat sensor cannot capture in the same way. 3D photography using two lenses has existed for a while, but viewing the result requires compromises relative to a print on paper or conventional screen technologies. The ability to have a shallow depth of field is valuable as a compositional tool to focus the viewer's attention where the photographer wants it. Bokeh - how the defocused area looks is an artistic quality, and so far the digitally-created version I've seen produced by smartphones is not aesthetically pleasing to me. I imagine that will change as the algorithms get better. I think some of the trends currently popular in photography using dedicated cameras are driven by what smartphones can't do, which includes (optical) shallow depth of field.
