So, we’ve got a bunch of improvements here that cross over from hardware to software and touch on user experience. All three Apple’s strong suits when it comes to integrated devices like the iPhone. If you peer more closely though, the biggest differences between an iPhone shooting experience and that of a traditional camera comes down to one thing: the image signal processor in the A7 chip.The aperture isn’t that much bigger than competitors and the pixel pitch is actually smaller than the HTC One, for instance. And the sensor, though increased in size, is very tiny when compared to even point-and-shoot cameras.The differences, then, come largely in how Apple’s ISP hardware and its front-end software mesh to make life easier for photographers. There’s a quote on Apple’s iPhone page which I think is nicely phrased:“It just makes more sense to teach iPhone how to take a great picture rather than teach people how to be expert photographers.”
