Something happened, folks. As if from nowhere, we've suddenly arrived at at a place where lens blurring techniques have suddenly shot up in popularity, particularly with Android manufacturers. Indeed, just a few months back, these techniques were seldom seen in the mobile industry, despite its deepening investment into the photographic capabilities of the devices it churns out. Regardless, now that it has caught on with the likes of HTC, Sony, and even Google, this trend has a pretty good chance of persevering and even proliferating. Or does it?
Bokeh: the fake kind, the real kind
So what does lens blurring have to do with words like UFocus, Background defocus, and bokeh, that you gleaned from the title? Everything, especially seeing as how they are one and the same thing. It's just a matter of speech (and branding). For those who are unaware of what a bokeh is -- fret not -- for no fancy explanation is required. Bokeh (or lens blurring) simply refers to the artistic quality of the blur produced in parts of an image that are not in focus. In other words, any parts of your composition that lie beyond the depth of field will appear blurred, and create the sometimes desired bokeh effect. That, at least, is how it works with traditional DSLRs (you can check out reference shots taken with the Canon EOS 6D at the very bottom).
