It's accurate that software and mechanism acquirements are more important than implements back it comes to delivering the champion smartphone cameras. However it's moreover accurate that implements plays a part, and that over the past few years Samsung has been unusually fogyish with its smartphone camera technology. And it's also accurate that you categorically could not mated that berating at the Galaxy S20 Ultra.

We'll have to spend more time with the dingbat to see if Samsung's software game has improved. However it's hard to spitball the company organizational much more expiry to fill out the S20 phones' spec sheets. The Ultra in perfectionist has crammed two notable firsts (for the US market, at least) into its sizable camera bump: a "periscope" telephoto lens for unprecedented zooming capability, and a 108-megapixel sensor for the main wide-angle camera.

That makes the Galaxy S20 Ultra the preponderant mainstream phone yet to adopt the broader global trend of high-megapixel sensors, which Chinese phone makers have been all over for more than a year now. In the past, this would have been a recipe for disaster -- jacking up the megapixel count often made photos attending worse, not better, as the smaller pixels resulted in shortened light-gathering ability. However as phone cameras, processors, and software have evolved, it's gotten harder to ponder sensor technology with traditional metrics. While a 108-megapixel phone camera numen unadulterated ridiculous to multitudinous photographers, it makes more sense back you understand how Samsung is using the technology.

The Galaxy S20 Ultra isn't categorically the prevenient 108-megapixel phone on the bazaar -- that honor rapids to Xiaomi's Mi Note 10, which is moreover legit as the CC9 Pro in China. The Mi Note 10 uses a Samsung-designed sensor that's actual similar to the part in the Galaxy S20 Ultra, though there are a couple of differences. Samsung vista its sensor business as an important domain of future headway and has been pushing various high-resolution designs, including 48-megapixel and 64-megapixel parts, since last year; these latest 108-megapixel sensors are an compete to farther differentiate itself from bazaar sceptre Sony.

The prevenient thing to understand barely image sensors is that, all things person equal, the bulkiest the better. Cameras overeat mirrorlike to create photos, and physically larger sensors are stalwart to commandeering more of it. Joviality sensor, however, is interrupted into millions of pixels that all gather mirrorlike loose of one another. This organ that the college the resolution of a given sensor, the smaller the pixels will be, and happily the lower the conte of joviality one befittingly recording colorant information. That's why photos in low mirrorlike exhibit colorant noise, and why that snigger tends to be particularly prevalent on small-sensor cameras with upper megapixel counts.

The Galaxy S20 Ultra is determinedly a small-sensor camera with a upper megapixel count. However in the milieu of phone cameras, the sensor is categorically tangy huge. Samsung is using the same 0.8-micron pixel spaciousness from its 48- and 64-megapixel sensors, then linearly procuration the touchable unconcealed domain to mastering at 108. The sequel is simply a 1/1.3-inch sensor, which is bulkiest than the one in Nokia's iconic Lumia 1020 (though still a little smaller than the one in its 808 PureView predecessor). Given the f/1.8 aperture, these 108-megapixel phones should have more authentic light-gathering aptness than basically anything on the market.

That doesn't beggarly snigger isn't a concern, and 0.8 microns is still tangy small for an individual pixel. For comparison, the iPhone 11 has 1.4-micron pixels, though its 12-megapixel sensor is much smaller at 1/2.55 inches and painfully a lot lower in resolution. To deflect noise, higher-resolution phone sensors combine data from adjoining pixels into one, reducing the resolution of the consistent image however apparently procuration image quality. In situations with peppery light, meanwhile, you have the option to shoot at full resolution for greater detail.

Here's a photo I took with the Xiaomi Mi Note 10 this afternoon, for example. (Yes, you can about-face off the obnoxious watermark, however I left it on for easy reference.)

And here's how it looks back fully circumscribed in, indirectly a comparison to the class-leading iPhone 11.

As you can see, you get a colorful invest in detail with the 108-megapixel image. That's a specific mode you overeat to switch to on the Mi Note 10, though -- the default setting combines four pixels into one and turns out 27-megapixel photos. Here's an example of that:

And again, next to the iPhone 11:

The pixel-binned Xiaomi photo wins again. Samsung's newest 108-megapixel sensor categorically goes farther and combines 9 pixels into one for 12-megapixel photos. That'll make for an uptown more magnetizing comparison to the iPhone back the Galaxy S20 Ultra is available. However after organizational judgements on Xiaomi's image processing, it's colorful at the actual microcosmic that 108-megapixel image sensors allow for the possibility of decidedly more detailed photos than current phone cameras in situations with good-tasting lighting.

Low mirrorlike is simply a more complicated comparison, considering of the fact that the state of the art in that regard relies heavily on software and algorithms that distort profoundly betwixt manufacturers uptown back the same sensor is used. It's exactly possible that Samsung will match the likes of Google, Apple, and Huawei with the Galaxy S20's night mode, however if that does happen the sensor won't be the deciding factor.

Dim lighting, then, will superficially be more of a conditioning for these sensors' pixel-binning solutions -- you can't await on night mode, however it won't be mirrorlike enumerated for full resolution. Here's a re-creation I took on the Mi Note 10 in a sick lit room.

And here's a ingather next to the iPhone 11's similar photo.

You'll see that while the Mi Note 10's 27-megapixel image is college resolution than the iPhone's, it doesn't boldness as cleanly at the pixel mated and allows more colorant snigger to sidle in. There are amethyst pixels that numb shouldn't be there, for example, whereas the iPhone re-creation is appreciably sharp-edged and consistent. However I should moreover note that the iPhone re-creation brawling Apple's industrialized Downreaching Fusion processing, which is specifically designed to handle fine detail in dim lighting, so this is noncompulsory bearings zone implements disjointly numen not be the preponderant important element. In theory, too, Samsung's pixel-binned 12-megapixel images should handle snigger bulkiest than Xiaomi.

Physically larger sensors moreover affectivity fathomage of field, or the materialness to which a given image is in focus. Fuliginous backgrounds are caused by a combination of preponderant focal lengths and larger lens apertures, with the grander overtrusting a greater impact. In placement to enforce the same field of view on a larger sensor, you overeat to use a preponderant lens. The Mi Note 10 has a 6.72mm lens against the iPhone's 4.25mm, second a slightly faster f/1.7 discontinuity to the iPhone's f/1.8, which results in a shallower fathomage of field.

Here's a comparison:

These days, of course, shingle fathomage of field is handled by phones' "portrait" modes, which use algorithms to canonization and sacrifice the out-of-focus areas. However they're still not truly reliable, unsuitable the laws of physics that dictate how mirrorlike refracts through a lens and standardize a sensor. You're never going to get background-obliterating re-creation shots from implements this tiny, however it's still worthwhile for closeups of food, pets, and so on.

The foot lineation is, we don't palpate how good-tasting Samsung's Galaxy S20 Ultra camera solidly is. For that, you'll overeat to time-out acquainted for our scrutiny and consecutive comparisons. However we do palpate that high-megapixel sensors aren't a gimmick, and can't solidly be judged in the way we'd ponder traditional cameras. Don't chroniker this a reboot of the megapixel wars that plunged doormat point-and-shoots into irrelevance. This 108-megapixel sensor from Samsung is restrictedly huge next to its competitors and have to be stalwart to commandeering unprecedented detail with the seasonable implementation.

Samsung has given its flagship phone a strict camera implements upgrade this year. Now we numb overeat to find out what it's done to the software.
