Camera - Daylight Evaluation

The P20 and P20 Pro’s main features are marketed to be the cameras. Although both devices are performant, and offer excellent battery life, to be able to justify the premium price range that they’re in requires a no compromise camera.

The main star here is the P20 Pro and its main 40MP shooter. At a 1/1.7” sensor size with 1µm pixels, it’s a huge piece that promises to vastly improve the capture abilities of the Huawei flagship. I noted during my initial hands-on in Paris while the 40MP had its ups and downs, the main feature that I was most impressed with was the 3x and 5x zoom capabilities of the camera which exceeded my expectations, so we’ll have a closer look at zoom-specific scenarios in this article.

First off before going into the analysis I’ll have to explain the many shooting modes that Huawei provides on the P20’s and sibling devices

  • 40MP/12MP – The native shooting modes on the main sensors, applies to the P20’s.
  • 20MP – For the P10 and Mate 10 this is the hybrid capture mode using interpolation between the 20MP monochrome sensor and the 12MP RGB sensor. Unfortunately not that great and it’s better to stick to 12MP in daily usage, although there are no negatives.
  • 2x Zoom – In the case of the P20 this is sensor interpolation, on all other devices this is 2x optical zoom on the secondary module.
  • 3x Zoom – Applies to the P20 Pro – uses the secondary optical zoom camera
  • 5x Zoom – Applies to the P20 Pro – uses the secondary optical zoom camera and interpolates with the 40MP main sensor.
  • “AI” – On the P20’s this is automatic scene recognition and it applies predefined settings based on that – sometimes this is beneficial, sometimes it’s detrimental, in many cases it’s not noticeable.
  • “Night” – Low light mode on Huawei devices which employs software based image stacking over long exposure times.

Starting off with the first scene, unfortunately I was forced to take pictures under cloud cover as it’s been a not so great couple of weeks here weather wise.

The P20 Pro offers the best and most natural result in its 40MP mode here as it was able to capture a balanced exposure. Once you shift over to the automatic 10MP mode the phone starts applying sharpening processing and in terms of detail it can be a hit-and-miss depending on the scene, and I found that to be rather a weakness of the P20 Pro as we’re seeing much better results from competing devices.

The AI feature here in this scene switched around between a HDR and SDR mode – both look unnatural compared to the simple 40MP shot that the camera is able to capture. In particular it seems the AI feature has a knack for applying a vignette filter, something that can be seen in most shots throughout this page.

Switching over to comparisons in the zoomed in photos, the P20 Pro just stands alone with no competition as it just has a raw advantage in terms of optical zooming capabilities over other 2x zoom modules. What I find interesting though is that the 3x zoom capture of the P20 Pro is by far the most accurate in terms of colour representation.

Even though there was cloud cover, I still found it shocking that phones such as the Galaxy S9 again fell on their faces in this scenarios as it happened to overexpose some shots and having to bring back down the brightness via HDR processing, resulting in quite a mess of a picture.

Another zoom-centric scenario is the close-up of a clock-tower. While in full frame, both the P20’s had large issues with the exposures and it was one scenario where the AI feature did help a lot as it entered one of the many processing modes of the camera. Competing devices here fared a lot better as they didn’t have issues in their default modes.

In terms of zoom capability, again it’s apples-to-oranges as the P20 Pro’s optics are just superior.

This next scene we again see different results depending on the capturing modes. Oddly enough, it’s best to remain in the 10MP mode and to ignore the AI suggestions as they are detrimental. In the full frame shots the P20 Pro actually loses out to all other phones and even the P20 as it really has trouble with balancing exposure correctly. The 40MP mode here is also of no use as the phone can’t expose correctly and the lack of OIS also results in a blurry image.

Zoom-wise, the 3x and 5x picture again seem to actually do far better exposure wise as they result in a very accurate representation. This shot also showcases the benefits of the 2x interpolation zoom on the regular P20 as it does manage to get slightly more detail in as the default 12MP mode.

The P20 Pro did well in both 40MP and 10MP mode – although it’s visible that the 40MP mode isn’t that far off in terms of detail sharpness and retention as the Galaxy S9+ for example. This is likely due to the 1µm pixels on the P20Pro’s sensor which are more prone to noise. At this point I’d like to bring up the various shooting modes of the P20 Pro and just how usable the 40MP mode is; to get the full 40MP you need to enter the settings menus and specifically select it. In this mode however, you no longer have the option to switch over to the zoom camera, which seems counter-intuitive. It also seems that some post-processing options are not available in the 40MP mode, so in some cases it’s likely that the shots in the 10MP mode will be superior.

This scene again in its full frame view has the same problems for the P20 Pro: While in 40MP mode, while there’s a lot of pixels captured, they are far less quality and retain less detail than the competing phones. The 10MP picture, while overall good, again just has a detail disadvantage virtue of the reduced resolution.

The 3x zoom in capture again results in the best overall detail retention for the P20 Pro, and it’s starting to look like a pattern by now. This scene is again an example of overall detrimental effects of the AI function, in particular in the 3x zoom mode as I’m not too sure why it thought it needed to darken the shot that much.

The P20 does quite well and it’s an immense upgrade over the results of the P10 and Mate 10 in this scenario.

This next scene is probably one of the most favourable ones to the 40MP mode as it just captures vastly more detail compared to other modes and other phones.

The last shot is again a controversial scene for the 40MP sensor – in the full 40MP mode the phone doesn’t seem to have that big of an advantage over the 10MP mode – the shop sign is clearly more detailed in the higher resolution shot, but then it has issues such as on the metal mesh of the garden chairs which are better defined in the 10MP mode. Comparing this in turn with the competing devices and I would have to give it to the S9+ in this scene, although the P20’s are competitive with all other phones. The larger issue here is again that it seems to underexpose too much and detail retention should come secondary after best exposure.

Thoughts on daylight capture experience

Overall I have a hard time judging the P20 Pro and to a lesser extent the P20. Huawei camera experience still seems extremely convoluted as it can’t seem to decide what camera mode is best for a given scene. In the past in Huawei devices this was limited to the choice of either shooting in normal auto-mode or in HDR mode, which you had to switch between in the shooting mode menus of the camera. The P20 Pro complicates this choice by adding into the fact that you don’t know for sure if your pictures are going to come out better in the 40MP mode or in the 10MP mode – again a switch that’s within the settings menu of the camera. To add even more complexity to the situation, we now also have an AI feature that sometimes does benefit but in my experience more often than not can actually be detrimental to picture quality.

Huawei needs to streamline this experience and do some better camera calibration in terms of what shooting mode is used in which scenario. I think Apple, LG and Samsung are currently among the ones that are leading in terms of shooting experience, because I know for a fact that the camera in the vast majority of the time will select the best mode and end up with the best result with consistency.

The 40MP mode on the P20 Pro can be a winner in well-lit scenarios – but again, you have to know that you want to be in the 40MP mode and for example don’t need a fast switch to the telephoto lens (Because it won’t be available). Once you shoot in 10MP mode, then generally the P20 Pro and also the P20 lose out in terms of picture quality as they aren’t as consistent in terms of exposure and don’t retain as much detail as the competition.

The telephoto lens of the P20 Pro is definitely the most impressive feature in terms of picture quality. As opposed to the main camera, every shot on the 3x zoom camera came out generally perfectly in terms of exposure and it maintained a large amount of detail. I think this is due to the OIS on the telephoto lens which isn’t available for the other sensors. While it’s understandable that Huawei wasn’t able to put OIS on the extremely large sensor of the P20 Pro – I don’t see why they avoided it yet again in the smaller P20 as it has a detrimental effect on picture quality, and as we’ll see later on, also video recording quality.

    I meant to say that I emphasised it in the S9 piece by bringing it up, praising Samsung for keeping it. I'll reword it here. Reply

    I personally found the noise vs noise reduction smear balance of the s9 much more appealing in the night shots Reply

    Me too. Huawei NR smears the most out of all the flagships (HTC's seems to smear the least, surprisingly) and the only thing in auto propping up that low light performance is that second 20MP monochrome, because the 1/1.7" 40MP main on its own is horrible, its low light performance alone is completely out of proportion with its sensor size (easily hands the win to S9 and Pixel2), even if you manually bin the 40MP's output down to 10MP its low light performance is good as useless, Phonearena already did such a comparison size-matching the output of the P20Pro 40MP and a regular Pixel2XL low light shot.

    Agreed! I think the author is out to lunch on this claim of his about the Huawei's supposed dominance in night shots. It clearly looks worse. Reply

    New Cameraphone: Huawei P20 Pro. Old phone" iPhone X.
    Enjoying my P20 Pro immensely! My regrets: not buying the "Twilight" version & buying an iPhone X in the first place.

    Why no comments or comparisons to the Google Pixel 2 in the camera pages? For me they still look the best in many cases (no pro photographer here though) Reply
  • Andrei Frumusanu - Sunday, June 17, 2018 - link

    I didn't want to comment on every single phone and kept the phones to a minimum - personally I did not like the Pixel 2's shots - too much tendency towards unnatural HDR processing in daylight and too much noise and fuzziness in the night shots. Colour accuracy is the Pixel's forte I must admit though. Reply

    They look good to me exactly because of their HDR! And their colour of course. Anyway, appreciate the reply! Cheers Reply

    No excuse for Huawei on their glaring 3 major flaws.

    1- Design copy of EMUI as iOS
    2 - Extended too deep as they just want to make the phone damn like an iPhone X with this Notch, camera module, the phone aesthetics, the plasticky frame look of that metal with polish like Apple again.
    3 - No Headphone jack, another inspiration from Apple.

    They want to be in serious front lines and all about their own AI powered notification system was a damn mess, I don't think it's going to be fixed anytime, Their lack of updates and price it to the north with tons of SKUs. After seeing the GSMA samples of Lumia 1020 Pureview, No camera comes close to that phone, they had Xenon flash, bigger massive sensor true lossless zoom and perfect natural colors unlike Huawei's AI crap or Samsung's oversaturated processing.

    Their recent fiasco of no bootloader unlock is another middle finger. Removing the jack driling holes like Apple. sheesh this phone doesn't even deserve any praise on the design front, and should be called out for it's cheap design, Only Huawei phone which is a true flagship was Mate 10 standard edition, no rounded drama, no notch, has a headphone jack, front scanner, 16:9 panel, SD slot. This phone doesn't have any of those or any phone from Huawei.

    Chinese phones nowadays have flooded the market with this obnoxious chin + notch BS and all phones are looking the damn same. A shame to the whole industry which Apple brought with their always fancy style over substance.

    No wonder no ones cares about audio anymore, soon LG will stop bleeding and ditch that ESS (half baked anyways needs mods to enable the HIM - High Impedance Mode as they crippled it unlike the older days SGS - Wolfson Linux driver compatible DACs) as they did with V20's removable battery and made an abomination G7 ruining the perfect balanced design, 19:9 is so impractical and useless, adding the chin (yeah I've said it by 3 times) it's just insane and stupid.

    Andrei shouldn't excuse them for adding a battery, Samsung's Note 8 has more tech inside it (ofc they played a stupid safe game of absurdly small battery) the stylus tech, Iris scanner, better construction and quality yet has a 3.5mm jack, S9+ improves on it, Note 9 rumored to have 3800+ mah (maybe it will help that failed Exynos 9810's custom kernel optimization) and have a 3.5mm jack again with SD Slot and all bells and whistles.

    Upcoming Pixel 3 XL having a notch, just ruins the Android now. Every OEM on the planet want to be like Apple. Sigh, Sorry for the long rant.

    Wow... It's just a phone. You sure do have strong opinions about this. Maybe use more full stops next time? Also IMHO, go get a life :) Reply
