3 Cameras On Iphone 11 Pro

Why does the new iPhone 11 Pro have 3 cameras?

On the back of the iPhone xi Pro can be found 3 cameras. Why? Considering the more than light yous collect, the amend your motion picture can be. And we pretty much reached the limit of what one camera can exercise a little while dorsum. Two, three, even a dozen cameras can be put to work creating a single photo — the only limitation is the code that makes them piece of work.

Earlier in today’due south announcements, Apple showed the base-level iPhone 11 with two cameras, just information technology ditched the telephoto for an ultra-broad lens. Only the iPhone Pro has the original wide, plus ultrawide
telephoto, its optical options covering an judge 35mm equivalent of 13mm, 52mm and 26mm.


“With these iii cameras you take incredible creative control,” said Apple’s Phil Schiller during the phase presentation. “It is then pro, yous’re going to dear using it.”

Previously the telephoto lens worked with the wide-angle camera to produce portrait mode effects or take over when the user zooms in a lot. By combining the info from both those cameras, which have a slightly different perspective, the device can determine depth information, allowing it to blur the background by a certain bespeak, amongst other things.

The ultra-wide lens provides even more information, which should improve the accurateness of portrait fashion and other features. 1 nice thing about a wide angle on a dedicated sensor and camera arrangement is the creators can build in lots of corrections so you don’t go crazy distortion at the corners or center. Fundamentally you’ll still desire to back off a chip, because using an ultra-broad lens on a face gives it a weird look.

While we’re all used to the compression-to-zoom-in gesture, what you’re usually doing when you do that is a digital zoom, just looking closer at the pixels you already have. With an optical zoom, however, yous’re switching between unlike pieces of glass and, in this example, different sensors, getting yous closer to the action without degrading the image.

One nice thing about these three lenses is that they’ve been advisedly chosen to work together well. You may accept noticed that the ultra-wide is 13mm, the wide is twice that at 26mm and the telephoto is twice
at 52mm.


The simple 2x factor makes it easy for users to understand, sure, simply it too makes the image-processing math of switching between these lenses easier. And as Schiller mentioned onstage, “nosotros actually pair the three cameras right at the mill, calibrating for focus and color.”

Not only that, but when yous’re shooting with the wide camera, it’southward sharing information with the other two cameras, so when you switch to them, they’re already focused on the same point, shooting at the same speed and exposure, white balance and and so on. That makes switching between them generally seamless, even while shooting video (just be enlightened that you
shake the device when you tap it).

Apple’south improvements to the iPhone camera system this year are nowhere about as crazy as the switch from one to two cameras made past much of the industry a couple years back. But a wide, tele and ultra-wide setup is a common one for photographers, and no doubt will prove a useful i for anybody who buys into this rather expensive single-device solution.
