Here's what Apple's iPhone 7 invitation tells us about the new phones

Apple has invited the press for what shapes up to be its biggest event for the year. The expected star of the show: the new iPhone 7 and iPhone 7 Plus, of course.

And while you've already seen so many leaks and rumors that your eyes probably hurt (we know our do), there's nothing like a good old teaser from Apple itself. A company known for carefully staging every detail of its presentation, it's no coincidence that people read Apple's every public move as a puzzle to solve.

And this time around, it's not even a complicated one, but we ought to mention the obvious: the blurred Apple logo is as clear of a hint as it gets towards the rumored dual camera feature on the iPhone 7 Plus. And while we all knew about its expected arrival, we could only guess its main use. Now, it seems clear: Apple highlights that you'll be able to 'see' some nice bokeh (which is that blurry background effect) with the new iPhone's camera.

Native bokeh is an effect achieved thanks to the physical properties of an optical system: the aperture blades of a camera squint to their narrowest, you move the zoom ring to its maximum telephoto length, and the magic happens. The focus locks on the subject plane, and everything in front and behind gets creamy blur. You can focus on your subject that really stands out.

Why can't we have this on a phone camera? Well, it's possible with macro shots, but there is no going around the laws of physics and if you want to shoot a portrait with a bokeh background, you'd be hard-pressed. And if Apple has managed to solve that issue in an elegant and non-destructive way, this would really be something special for image lovers. These days, everyone is a photographer, after all.
