Is 13 Mp Camera Resoultion Good
Buy any smartphone, and 1 of the headline features will be the megapixel count of the cameras that come on the device. Frequently the front "selfie" camera will take a lower megapixel count than the camera (or cameras) at the rear of the phone, considering you're usually belongings the photographic camera a lot closer to your face up at the forepart than the subject yous're shooting at the rear.
We've reviewed and tested the market's top smartphones, looking at low-low-cal performance, forepart-and-rear facing cameras, movie settings, detection AI and more. The all-time cameras we've tested to appointment are on the Huawei Mate 20 Pro, the Samsung Galaxy S9+ and the Apple tree iPhone XS Max.

To understand what a megapixel is, you demand to understand what a pixel is. A pixel is, in visual and technology terms, a unmarried dot in a visual image.
Thinking back to the bad old days of CRT TVs, if you stared really closely at the screen, you could make out the individual trivial cerise, blue and greenish onscreen dots. Each of those was a pixel. Stare closely at your LCD or OLED TV and y'all probably won't see the same affair, because today'southward TVs (and any other digital brandish) tend to pack in millions of pixels into the same space, leading to crisper images that announced more natural.
Each pixel'southward task in a digital photographic camera of any blazon is to capture the epitome information of whatever you're pointing the camera at, relative to the reflected lite from that object. A megapixel (MP) is a count of the number of pixels in an epitome, where the mega- prefix denotes a million. Then an 8MP smartphone camera contains a sensor with eight one thousand thousand pixels, a 16MP camera has sixteen million pixels on its sensor and so on.
There's no absolute difficult and fast respond to this question, because it depends on how you ascertain "need". In the context of images, the most important consideration is how and where you intend to display them.
Information technology'southward viable to print lower-megapixel photos at larger sizes, but typically a higher megapixel count will allow you to more comfortably impress A4 or poster-sized photos simply because at that place'southward less "stretching" needed to expand the image to the desired size.
What about if y'all're only ever showing your photos on a digital screen? There, you can use some simple maths to make up one's mind a minimum megapixel count. A Full HD Telly, for case, has a pixel count that equates to simply 2MP, and so annihilation higher than that will be scaled downwardly when shown on the screen. If you're viewing images on a 4K display, that effigy bumps upwardly to 8MP.
These days, the reality is that just well-nigh any phone that isn't a pure budget handset is likely to shoot at 8MP or ameliorate, and that's non a tendency that'southward going to reverse suddenly. If you never plan on printing concrete photos, a college megapixel count isn't going to be quite as critical a gene, although at that place are other areas where it can be surprisingly handy.
Using a higher megapixel rating to create a zoom is one of those areas. We have seen a smattering of photographic camera/smartphone hybrids, such equally Samsung's Galaxy Zoom or Panasonic'southward Lumix CM1, but for the most part, truthful optical zoom higher up 5x isn't something you get on a smartphone. What you can do however is the digital equivalent of zooming in past cropping a college megapixel photo down to a lower megapixel equivalent.
That sounds confusing, so here'south a quick example. If you lot took a photograph of a bird that was flight far away, y'all might only become i shot with a 16MP camera. That gives you a shot with four,920 by 3,264 pixels in it, but the bird might be the bodily signal of interest in the shot, with a lot of blue sky that you don't really want. On a traditional camera with optical zoom, you'd simply zoom in to brand the bird more of a focal point.
Using digital zoom, on the other hand, you might cut down the prototype to say 3008 by 2000 pixels, making the bird much more than of the focus of the shot and ending upwards with what is effectively a 6MP photo from your 16MP original. Crop in closer to, say, 2048 by 1536, and yous'd have an even closer shot of the bird at 3MP resolution. It's entirely viable that fifty-fifty with then much cropping, the resulting image could be reasonably pleasant, although it will obviously non pack quite so much detail equally if yous were able to get up close with your avian friend.
Where this becomes a bigger event is if y'all're using a phone with a less-powerful photographic camera. On a 3MP camera, for case, cropping in would bring the resolution much farther down, leaving you with a blurry bird shot potentially adequate as an online avatar pic but not useful for print purposes.
The 1 notable downside to a larger megapixel photo is that you've got to store all those pixels somewhere. If yous're always shooting at the maximum capability of your smartphone, you lot'll apply up a lot more infinite than if you shoot at lower resolutions. (If you set up your telephone to automatically upload pictures to a deject service like iCloud, Google Bulldoze or Dropbox, yous'll also chew through a lot of information.)
Most smartphone photographic camera apps allow you to set the megapixel count of each shot, so if you're using a telephone with fixed storage, like an iPhone of any generation or one of Google's Pixel phones, turning the resolution down on your shots can be a dandy way to save local storage space. Bear in mind with the Pixel phones that Google provides (for the time beingness) unlimited online storage to lessen the strain on your local storage.
What'southward important to realise is that when it comes to image quality, it's not just a raw numbers game.
A smartphone with an 8 megapixel camera might actually accept improve pictures than i with a 21 megapixel camera, irrespective of camera operator skill.
That's considering there'southward more than to taking images in a variety of situations than just cramming a higher megapixel count into a camera.
Kickoff of all, there'due south the size of the individual pixels to take into consideration, especially if yous're shooting in depression-lite situations. Some smartphones such as Apple'south iPhones take cameras with lower megapixel counts just larger individual pixel sizes inside that overall count.
That matters, because the function of each pixel is to capture the low-cal from whatever you're pointing the camera at. A larger pixel size – measured in nanometers – allows more light to brand its way to the sensor, which means it'southward more sensitive to lite in about situations. The larger the pixel size, the larger the overall sensor and the better the general capabilities of the smartphone camera.
Software can besides play an important office hither. Many smartphones offering camera apps finely tuned to the specifics of the onboard camera eyes on that phone, making them amend or worse than other smartphones even with the same raw megapixel count.
So at that place's the issue of phones with dual lenses, each with their own optical quality. Dual lens camera phones are very big right now, just there's a broad array of approaches when it comes to what you do with that secondary lens. We're even starting to see more phones emerge with up to 3 lenses, providing a lot of potential photographic flexibility, although it'south important to know the specifications and uses of those lenses because there's a wide number of approaches to the multi-lens problem.
Some phones, such as the Apple tree iPhone XS or Samsung Milky way S9 Plus offer a secondary telephoto lens. Others offer wide bending lenses, such every bit LG's G7 ThinQ.
Some phones have experimented with lenses that only shoot in monochrome, every bit is the case with Huawei's P10 Plus and Mate 10 handsets. This is both for the consequence and in order to mix colours between both lenses for a more pleasing overall picture.
Some dual lens cameras in the mid-range tend to take very low megapixel secondary cameras that are in that location purely to provide photographic "bokeh", or background focus blur, and on those phones you typically can't access the secondary camera as a separate entity. Instead, it's just a depth sensor to requite your portrait photos a fiddling more refinement.
Above that, different camera apps give you varying levels of control over your smartphone's functionality, from whether or not it'll shoot in RAW format to shutter timing and even specific modes for selfie shots to "beautify" your face – although results at that place tin can vary quite widely.
Information technology's worth pointing out that it is perfectly feasible to take very good photographs with a lower quality or smaller sensor. There are always the issues of composition skill and timing to accept into account. Having more tools in your camera toolbox, fifty-fifty with a smartphone photographic camera, gives you lot more possibilities, just it won't automatically make you a better lensman.
Some smartphone cameras as well feature optical image stabilisation. This packs tiny sensors into the camera lens to observe and correct for the minute vibrations that your easily make when taking photos. The practical effect of all that engineering science should be a significant reduction in the amount of blur in your shots, although once again the minor scale of smartphone cameras means that they can't use equally much correction as on a "full" lens camera such as a DSLR.
In that location really isn't a hard and fast dominion that tin declare a given camera "best" for, say, Instagram, Facebook or Flickr, considering the reality of each given photograph should be judged on its ain merits.

We'll judge how much mobile information you demand and how to manage your usage.
If, however, you're very serious about your smartphone photography, you're going to largely want to concentrate on the premium end of the sector, because this is where virtually phone manufacturers combine the majority of their smartphone camera blueprint smarts.
Again, you can take swell shots with an ordinary smartphone photographic camera, but the cheaper models often take very slow startup times, and so you miss shots, or slow focus speeds, so yous may end upwards with blurry photos.
With so much variation in megapixel count from smartphone to smartphone, it'south like shooting fish in a barrel to forget where your electric current telephone sits in the hierarchy of photographic camera resolutions. If that'due south the case, at that place are a few different ways to check the megapixel count on your photographic camera depending on what information you accept handy and what specific device y'all're using.
The simplest way to determine the megapixel count of your phone'due south cameras is to bank check the manual. Almost manufacturers provide technical specifications in the documentation that comes with your phone, so provided you've kept it and tin can ferret it out of the closet, you lot should be able to check the megapixel counts for all the cameras on your current handset.
Of grade, at that place'south a adept take chances that documentation went out with the trash or into the dark recesses of your wardrobe presently afterward you unboxed your new telephone. Don't fret: yous still take enough of options for getting the information you desire.
Checking megapixel count on an Android telephone
If y'all've got a relatively recent Android smartphone, checking the megapixel count is quite easy. Just open the photographic camera app, click the settings icon (the small cog) and you should find the megapixel information listed under the heading "Photo size". This settings page provides information specific to the camera you're currently using, so you'll have to back out and swap between the front and rear cameras from the main camera app to view the megapixel counts for both.
Older versions of Android and some specific camera apps might not display the megapixel count and then clearly. In this case, you tin can calculate it yourself past taking a photo, opening your telephone'southward gallery and clicking the data icon (a lower-case i). Here you should find the resolution of the photo in the form of width x length. By multiplying the two values together, you'll attain the megapixel count of your camera. For example, if the resolution of the image was 3024 x 4032, the result would exist 12192768, or 12MP.
Checking megapixel count on an Apple iPhone
Since in that location are far fewer iPhone models than there are Android smartphones, determining the megapixel count of your current handset is relatively simple. Open the Settings app, click General so click About. Here yous'll find your iPhone's Model number (likely in the grade of A1234). Compare this number confronting Apple's list of iPhone models to decide what model of iPhone you have.
Once you know which iPhone you lot're rocking, use the tabular array below to confirm the megapixel count of your iPhone's front and rear cameras:
No, or at least not yet. You tin can easily buy a smartphone for a couple of hundred bucks with a megapixel count that'south identical to that of a high-end DSLR that could price several one thousand for the camera body lone, let alone the lenses to go with it, simply the gulf in terms of photographic possibilities is immense.
What is articulate with the current crop of smartphone cameras, especially in the premium space, is that they're certainly good enough for most everyday purposes, especially if you're only sharing shots online or viewing them on a smartphone screen. There'south very fiddling example for most compact bespeak and shoot digital cameras because of this fact. Where nosotros've seen the biggest leaps in contempo times has been in low-light performance on the smaller sensors on premium phones, making it easier to go pleasing shots even afterward the sunday has gone downwardly.
In the more budget-axial space, while you may see a camera touted as being anywhere from 8 to 21 megapixels in pure pixel count, it's not the just consideration to bear in mind when assessing its overall photographic quality.
