Most notably, the processing gives the foreground a bit of a haircut, which you can see clearly in this example. I posted some samples on Instagram, using an unforgiving split-screen effect that dramatically highlights the imperfections of the processing. I took some shots where the Depth Effect shined, and some where it flopped. When I first started testing Portrait Mode, I was alone in my backyard, with only inanimate props. This process can never be perfect, but can it be good enough? The result is a photo with simulated shallow depth of field. This nine-level depth map is used to drive a variable-radius blur. Under the right circumstances, this mode enables a so-called 'Depth Effect,' where both cameras fire simultaneously, and a depth map is built based on the subtle stereo disparity between the captured images. Portrait Mode, Depth EffectĪpple calls their initial two-lens computational photo offering Portrait Mode, and the most recent developer beta of iOS 10.1 includes a beta version of it. It's entirely possible that they are using multiple exposures to aid in this process, but I don't know if anyone's ever confirmed that. Turns out Apple's been doing a ton of noise reduction on their photos for a few generations now. The first thing you notice when shooting raw DNG files with your iPhone is how noisy the image are.

Adobe jumped on this right away with Lightroom Mobile, having already implemented raw in their Android version. We've gotten to test this first hand recently with Apple opening up raw capture to developers. But even when the iPhone snaps a single, non-HDR exposure, the amount of post-processing it does is considerable. Already the iPhone will automatically perform an HDR merge of two exposures, for example. But can you do computational photography? That's a trick question, as the iPhone, and many other mobile phone cameras, are already doing computational photography. I'm pretty sure that with only two cameras, you can't build a useful light field. Computational Photography is Here (and Has Been for a While actually) That's what Lytro is doing with their plenoptic Cinema Camera (see previous post), and more analogously, what Light is promising with the 16-lensed L16 camera ( two posts on that one so far). Two cameras don't really make for a light field camera, where a computer model is built of the captured light rays, allowing them to be projected onto a virtual image capture plane, through a synthetic aperture.
