Why does the new iPhone 11 Pro have 3 cameras (Wide, Telephoto,Ultra Wide Camera)?
On the rear of the iPhone eleven professional may be found 3 cameras. Why? as a result of the additional light-weight you collect, the higher your image may be. and that we just about reached the limit of what one camera will do a bit whereas back. Two, three, even a dozen cameras may be place to figure making one exposure — the sole limitation is that the code that creates them work.

On the rear of the iPhone eleven professional may be found 3 cameras. Why? as a result of the additional light-weight you collect, the higher your image may be. and that we just about reached the limit of what one camera will do a bit whereas back. Two, three, even a dozen cameras may be place to figure making one exposure — the sole limitation is that the code that creates them work.
Earlier in today’s announcements, Apple showed the base-level iPhone eleven with 2 cameras, however it ditched the exposure for Associate in Nursing ultra-wide lens. however the iPhone professional has the initial wide, and ultrawide and exposure, its optical choices covering Associate in Nursing approximate 35mm equivalent of 13mm, 52mm and 26mm.

“With these 3 cameras you’ve got unimaginable inventive management,” aforesaid Apple’s Phil writer throughout the stage presentation. “It is thus professional, you’re attending to love victimization it.”
Previously the optical lens worked with the optical lens camera to supply portrait mode effects or take over once the user zooms during a heap. By combining the data from each those cameras, that have a rather completely different perspective, the device will confirm depth information, permitting it to blur the background past an explicit purpose, among alternative things.
The ultra-wide lens provides even additional info, that ought to improve the accuracy of portrait mode and alternative options. One nice factor a couple of wide angle on a frenzied detector and camera system is that the creators will integrate uncountable corrections thus you don’t get crazy distortion at the corners or center. basically you’ll still need to back down a small amount, as a result of victimization Associate in Nursing ultra-wide lens on a face provides it a weird look.
While we’re all wont to the pinch-to-zoom-in gesture, what you’re typically doing once you do this could be a digital zoom, simply wanting nearer at the pixels you have already got. With Associate in Nursing optical zoom, however, you’re change between completely different items of glass and, during this case, completely different sensors, obtaining you nearer to the action while not degrading the image.
One nice factor concerning these 3 lenses is that they’ve been rigorously chosen to figure along well. you will have noticed that the ultra-wide is 13mm, the wide is double that at 26mm and therefore the exposure is double that at 52mm.

The simple 2x issue makes it simple for users to know, sure, however it additionally makes the image-processing scientific discipline of change between these lenses easier. And as writer mentioned onstage, “we truly combine the 3 cameras right at the mill, calibrating for focus and color.”
Not solely that, however once you’re shooting with the wide camera, it’s sharing info with the opposite 2 cameras, thus once you switch to them, they’re already targeted on an equivalent purpose, shooting at an equivalent speed and exposure, white balance so on. that creates change between them largely seamless, even whereas shooting video (just bear in mind that you just can shake the device once you faucet it).
Apple’s enhancements to the iPhone camera system this year square measure obscurity close to as crazy because the switch from one to 2 cameras created by a lot of of the business one or two years back. But a wide, tele and ultra-wide setup could be a common one for photographers, and little question can prove a helpful one for everybody WHO buys into this rather high-priced single-device resolution.
