How the OnePlus 7 Pro’s cameras were tuned

One in every of the greatest products to return out from OnePlus is its very first smartphone, the OnePlus One. The OnePlus One was a no-name underdog competing towards established giants, and compete it did. The gadget catapulted this new and quite unknown Chinese brand to a name that was being extensively praised for its disruption to the flagship phase of Android smartphones inside mere months of its launch. Quick ahead a number of years, and the firm that when made the flagship killer now focuses on making flagships that attraction to a wider viewers and command larger costs. Others have now adopted the “Flagship Killer” moniker which OnePlus has long deserted; in the meantime, OnePlus has educated its guns on the premium tier of flagships with the formidable OnePlus 7 Professional. That includes a number of firsts for the OnePlus lineup, the OnePlus 7 Pro is undoubtedly considered one of the greatest smartphones to be released this yr. What stops it from being the greatest smartphone for this yr on all fronts is mockingly one among its headlining options — the digital camera.

Lots is claimed about the OnePlus 7 Professional and particularly, its digital camera. The OnePlus 7 Pro is an enormous leap for OnePlus when it comes to digital camera hardware, as that is their first gadget to function a triple rear digital camera setup with the 48MP Sony IMX586 as its main sensor. This, coupled with the very excessive DxOMark score of 111, meant that consumer expectations from the digital camera were naturally sky excessive. So when reviewers and customers mentioned that the flagship telephone had a mediocre digital camera, the firm was sure to take notice. Promises were made, and updates were rolled out. Whereas the debate nonetheless continues on how good the OnePlus 7 Professional digital camera actually is, OnePlus provided to offer us a deeper take a look at what goes on behind the scenes at their Image R&D Middle and Digital camera Lab in Taiwan, and to offer us the opportunity to immediately work together with the people who make the digital camera happen on OnePlus units.

Disclosure: OnePlus sponsored a tour of their Image R&D Middle in Taiwan. A number of media personnel from India, Europe, and China were flown to Taipei for the similar tour. OnePlus is a sponsor of XDA-Builders, but this journey was not related to stated sponsorship. The views expressed in the article are the writer’s personal and aren’t influenced by both of those sponsorships.

Digital camera Lab Tour

OnePlus has a dedicated office set up in Nangang district, Taiwan, where staff from mainland China, Taiwan, and India work majorly on digital camera and imagery related-aspects of present and future units. The Image Workforce follows its own mission assertion: “to make people confident taking photos on OnePlus.” The corporate’s inner knowledge unsurprisingly reveals that the majority of its users take pictures utilizing the telephone’s Auto mode, without fiddling round with any settings. This mission assertion thus performs into the shopper’s utilization sample to function the guiding philosophy for OnePlus’s Picture Staff.

The tour of the digital camera lab started with a take a look at a number of of the gear utilized by the workforce to check totally different parameters corresponding to white stability, exposure, distinction, colour accuracy, and readability. Main objective testing within the digital camera lab is completed by means of the use of systematic charts. Certain processes utilize automated exams to attenuate the variances that creep in via guide testing so that the solely thing that modifications between two outcomes is the firmware that’s being examined.

As an example, the setup above utilizes the carnival experience toy to assess focus tracking. The chart under the carnival journey has LEDs shifting alongside at totally different speeds, which again is used to evaluate focus. You may as well spot charts like the TE42, TE188, TE230, TE265, TE269 and so many more used at numerous locations relying on what needs to be tested at that stage.

The Spectralight QC, pictured above on the left, is a light-weight booth that emulates seven several types of mild sources, including natural daylight, and is used to evaluate colour accuracy underneath these lighting circumstances. The LE7 from Picture Engineering, pictured above on the proper, is a uniform lightbox that comes with transparent check charts and iQ-LED V2 mild sources. This machine once more replicates numerous mild sources in a check lab setting.

The staff is most pleased with the robotic arm gear which lets the group utterly automate a number of images situations, thus eradicating the human variance in these exams. The arm has room to maneuver with precision and consistency every single time, so even the smallest of modifications might be tested in the very same situations. OnePlus additionally has mannequins and a number of other other props so as to add in several sets of variations when wanted.

It wasn’t shocking to seek out that OnePlus also has racks filled with units hooked up to constantly run via a process listing of opening up the digital camera app and clicking a photo, to figure out whether the telephone can stay as much as heavy and continuous use.

The aim of these workouts is to determine the greatest set of optimizations in the software program to supply the greatest set of pictures. However as the saying goes, “Beauty is in the eye of the beholder” — so is the case with the pictures we click on our smartphones, making it essential to comply with up these objective checks with subjective testing. The subjective checks tasks engineers round a number of OnePlus workplace places (and hence totally different latitudes) to test out hardware and software program underneath a variety of circumstances to emulate real-world consumer conduct.

While objective and subjective testing do type essential parameters for assessment, OnePlus also bases its firmware modifications round consumer feedback and never merely employee outlook (which may typically grow to be too technical and lack emotion and join). While everyone can declare to take heed to the group, we see more proactive and protracted engagement from OnePlus via its Open Ears packages. These packages deliver collectively vocal customers and give them a platform to air their grievances and convey them on to the attention of the people who will work on these modifications. We had the probability to personally attend the Open Ears forum for the Developer Group in Goa prior to the OnePlus 7 Pro launch, and prima facie, it did permit several outstanding developers direct entry to the very people who can bring about results.


Similarly, during this tour, journalists and know-how bloggers had the opportunity to work together instantly with the engineers from the digital camera staff, allowing us to air our considerations and expectations while giving the engineers reside suggestions on their work. The group inspired dialogue and requested clarification wherever wanted, displaying an inclination to truly take heed to feedback. It is too early to predict whether most of this suggestions will get translated into actual enhancements; nevertheless, the mere incontrovertible fact that they listened and even allowed precise engineers (and never PR equipment) to pay attention, sets OnePlus aside from a number of of its rivals.

Function Parity

Certainly one of the largest requests from our collective finish was function parity across the totally different rear cameras, as we envisaged situations where the consumer can use totally different lenses in several modes seamlessly. OnePlus commented that some differentiation can be inherently present between the totally different lenses because of the features they serve, but the group does agree with the basic sentiment they usually do have function parity as one in every of their end objectives.

Zero Shutter Lag

We additionally brought up the situation of shutter lag (i.e. lacking Zero Shutter Lag) on the OnePlus 7 Pro. Despite being one among the fastest Android smartphones out there, there’s nonetheless a very small however noticeable delay when a photo is clicked. Surprisingly, OnePlus Co-founder Mr. Carl Pei, who was sitting with us in the audience, clarified our expectations from such a function to the engineering staff on-stage. In consequence, the engineering staff had better clarity on what we as reviewers and energy customers expected out of the world’s quickest Android smartphone. Despite the fact that no guarantees were made in the direction of several of those function requests, what’s reassuring is the incontrovertible fact that the individuals at OnePlus, proper from the co-founder to the actual engineers, were receptive in the direction of understanding the shortcomings of their product. That they had already poured blood, sweat, and tears into what they believed was their good product, solely to listen to from us that what is perfect in their eyes still had flaws. And the dialogue nonetheless continued to circulate brazenly.

Day Zero Updates

Another scorching matter throughout the discussion was the lack of high quality Day Zero updates. With the OnePlus 7 Professional, customers had significantly greater expectations right from the day of its availability but were majorly disillusioned with what they received out of the field. Several weeks later, OxygenOS 9.5.7 was rolled out, promising a lot better digital camera high quality, and the common consensus is that the update did enhance the digital camera by an honest margin. The query that we put forth to the OnePlus group was why a big update like this not made obtainable right at the time of launch, as the availability of 9.5.7’s enhancements right out of the field might have improved market perception in the direction of the weakest point on an in any other case nice product. What customers ended up buying felt rather a lot like an incomplete product, with the experience being equated to hyped video video games which are launched in a half-finished state after which made complete with later DLC’s — this “launch now, fix later” angle is unacceptable and shouldn’t be the norm in any business. The group on-stage clarified that there are vital testing procedures to be adopted, which inevitably ends up taking plenty of time. The 9.5.7 replace was additionally a direct consequence of the suggestions that the staff acquired from reviewers and early users, so the modifications caused by the update were direct requests from finish users, something that isn’t attainable to gauge before users can get to truly use the product. At this stage, Mr. Pei chimed in as soon as once more, but not to justify the staff’s actions, however somewhat to simply accept that users do anticipate perfection at launch from such a premium product; if OnePlus already has these check labs and large beta packages in place for testing and suggestions, why isn’t the product in a lot better shape proper from day zero? Mr. Pei stepped in to make clear our factors and let the product staff know what users truly needed, and that this was coming straight from the customers themselves (us in this state of affairs), and never merely instructions that were flowing down the company hierarchy. Naturally, the workforce didn’t yet have a solution to a question like this, but they did walk away with a better understanding of the market’s expectations. Hopefully, this suggestions gets included into the next product.

Regional Expectations

What additionally got here up during the dialogue is the difference in expectations of users in several areas. For example, users in Europe favor natural seems for selfies and portraits, while those in India, China, and other elements of Asia are usually inclined in the direction of magnificence mode filters and different synthetic processing. For OnePlus as a worldwide model, the Picture Staff must strike the proper stability to satisfy as many users as it will probably, and such a majoritarian strategy will inevitably lead to situations where not everyone shall be glad. A potential answer might be to current totally different setups to totally different regions to satisfy their specific expectations, and the group acknowledged this as a potential path for his or her future work.

Interview with Mr. Zake Zhang

In conversation with Zake Zhang, Image Product Manager

After the digital camera lab tour, I had the alternative to take a seat for a quick dialog with Mr. Zake Zhang, the Picture Product Supervisor at OnePlus, wherein we talked about the DxOMark controversy and managed to eke out ETAs for a couple of features.

Aamir: “Is there an explanation available for the DxOMark controversy? Statements made by Szymon do not align with statements made by OnePlus.”

[That is just about the OnePlus 7 Professional’s DxOMark rating of 111. In their evaluation of the digital camera, DxOMark famous that “the camera firmware used for the DxOMark tests is not yet currently available to consumers. OnePlus will make it available as an over-the-air update before the end of the month.” OnePlus insisted that the construct obtainable to DxOMark for his or her testing was, in reality, the similar retail firmware obtainable for patrons. Afterward, when OxygenOS 9.5.7 replace was launched, OnePlus India’s Product Supervisor Szymon Kopec tweeted “Just go and download that new software. That’s our 111 points DxO build.” This tweet contradicted previous claims.]

Zake: “From the first day, everything is exactly the same as the version we sent to DxOMark for testing. How we need to understand this is that what looks good on paper won’t really tell you what people want from a camera. We do as much as we can, we work closely with DxOMark and get the camera right, but the users say it’s not enough.”

Aamir: “The way that DxOMark scores camera, their methodology is different from what a user wants from his camera. That’s why the Pixel has a very low score even when it performs very well.”

Zake: “Right. After the launch, we take in people’s feedback and start to implement their preferences into the camera, tuning and adjusting it. And people are quite happy with that. What Szymon said was taken very literally, it was in a different meaning. He meant more as a justification towards the high DxOMark score.”

Aamir: “Moving on, everything in the premium segment usually has a burst mode coupled with a smart selection method [intelligent burst mode/smart capture/best shot capture]. This takes the thinking out of the process [of selecting one good photo]. Is this something we can see implemented in a OnePlus device?”

Zake: “This is a feature that is already included in current software. You need to use our own Camera app to click the picture and Gallery app to view the picture set. The Gallery app will suggest the best.”

[We checked it out, and it indeed existed on our device, OxygenOS 9.5.9 for reference]

Aamir: “OnePlus often gets associated with OPPO in some way. OPPO has been working on some creative camera technologies lately like the in-display camera and optical zoom setups. Is OnePlus working on something similar, as people presume that you share resources between yourselves?”

Zake: “For each OnePlus project [with reference to the camera team], we actually work from the ground up. We do not share, it’s not like OPPO has already worked on something and we can take that directly from OPPO. Our companies are run separately, which means our camera team is also separate. We pick our own camera hardware, we work on our own camera software. We make our own choice for hardware. For OnePlus 7 Pro, we have 7P lens which is not something OPPO can do, you need to make a different order to the provider. It is separate.”

Aamir: “Can you share a timeline for video recording by way of the vast angle lens?“

Zake: “We are in internal testing phase, and we plan to roll out the feature later this year.”


This trip to the OnePlus Image R&D Middle was an enlightening experience, for it allowed us an insight into what goes on behind the scenes when the changelog just mentions “Camera fixes and improvements.” Whereas OnePlus’s Digital camera Lab is spectacular in its own right, we wouldn’t be stunned to study that giants like Samsung, Google, and Huawei have greater groups and higher assets devoted in the direction of their imaging departments. What does surprise me constantly is OnePlus’s capability to take heed to suggestions from finish customers and making an attempt to include these classes inside their products. Hindsight is all the time 20:20, and it is extremely straightforward to point in the direction of past failures and decide them apart. What matters then is what one takes away from errors and what is finished to ensure they don’t seem to be repeated. We hope OnePlus continues on enhancing themselves.
