Camera - Low Light Evaluation

It’s hard to argue against the fact that over the last 2 years, Apple has largely fallen behind in terms of low-light photography. The advent of computational photography with new dedicated night modes, along with competitor devices which have massively more performant camera hardware, meant that the iPhone XS ended up being one of the least competitive devices in low light conditions. Some developers out there have even tried to address this gap with third-party camera applications which deliver their take on computational photography night mode capture.

Apple seems to have made note of this and the new iPhone 11 series now does address this missing feature. Let’s see how it holds up against the fierce competition:

Starting off with a low-light, yet still artificially illuminated scenario, we encounter the first aspect of Apple’s new camera: the night mode isn’t a dedicated mode that one can manually select. Rather, it's a mode that gets triggered automatically depending on the ambient light detected by the phone. In this scene, there was too much light available, and as such the phone wasn't able to trigger Night mode.

That isn’t to day that the iPhone falls behind, the main camera is still very much able to produce some excellent results. In such medium light scenarios, the telephoto lens’ wider aperture now allows the camera to actually use the module rather than falling back to the main sensor and cropping the scene, which is what the XS did.

Unfortunately, the wide-angle lens’ results here are just bad and it’s all just blurry. Huawei and Samsung clearly both dominate here in terms of low-light quality, with either better sensors such as the Mate 30 Pro, or making use of Night Mode on the wide-angle unit, something which isn’t available for the iPhone 11.

Going to a darker scene, we now finally see Apple’s Night Mode in action. Apple’s non-night mode shot is actually more representative of the actual brightness of the scene at the time, but Night Mode really improves the amount of detail throughout the scene. Apple’s implementation here is superior to Samsung’s and Google’s, as it’s able to retain more detail and has a better handling of the noise. Samsung has the odd situation that the new Night Mode on the Snapdragon variants is inferior in quality to the Exynos based models, making things quite blurry. Huawei’s specialized low light RYYB sensor still is the best low-light camera.

It’s odd to see that Apple’s algorithm doesn’t attempt to bring down the highlights, as such the signs on the left which are still very much blown out and overexposed.

I tried to capture a picture with the Night Mode exposure set to the very maximum 10 seconds as made available in Apple’s camera UI, however the end result was always repeatedly always capped at the exposure the camera automatically selected, even if it did appear as if it’s capturing a 10 second shot. I retested this on the newest iOS 13.2 and things did change, as it was indeed able to capture a very different shot – so it seems the Night Mode behavior on iOS 13.1 is still bugged.

The iPhone’s 11 series' wide-angle module continues to be pretty terrible in low-light.

Apple’s night mode here continues to impress as it’s able to reproduce an excellent representation of the scene with a lot of detail. Google’s Night Sight is comparable, or even better, in detail, however the colors are too vivid.

We continue to observe that in more well-lit scenarios that the night mode doesn’t engage. Even without it, the new iPhone 11 is an improvement over the XS.

The wide-angle module remains terrible and frankly I’m a bit puzzled why it does so bad even in a more well-lit scene like this one. The phone gets pretty much embarrassed by all the other devices.

One thing we notice about the new Night Mode is that it’s not really able to bring out details in areas where the sensor doesn’t see anything. For example, in this scene the roof of the abbey remains clipped to black, while other devices such as the S10 or the Pixel are able to bring out the roof’s structure and details. The darker it gets, and as long as there’s some brighter elements to the scene, we’re seemingly hitting dynamic range limitations on Apple’s night mode.

In more uniformly dark areas, the iPhone is able to extract a ton of light, but in areas where the sensor just isn’t sensitive enough and it’s not able to provide any data for the algorithm to accumulate over time, it leads in some odd looking results such as this extremely pronounced shadow of the play castle.

Here again, in a very uniformly lit but still extremely dim scene, the iPhone 11 is able to bring out a ton of light and the result here is significantly brighter than how the scene was in reality. The iPhone beats Google and Samsung in terms of detail and only Huawei’s devices remain as the better rivals.

Low Light Conclusion – A Much Needed Feature Added, Wide Angle Lacking

Overall, Apple’s addition of the new night mode very much elevates the camera capture ability of the iPhone 11 series. It was as solemnly needed feature given that almost all other vendors in the industry have embarked on the computational photography train.

Apple’s implementation shines in a few regards: First of all the fact that it gets selected automatically rather than it being a dedicated mode that you have to switch to is a significant plus. as well as a very large practical advantage over other vendor’s camera experiences.

Quality-wise the pictures that the iPhone 11 series is able to produce in low light is top of the line and is challenged only by Huawei’s massive specialized camera sensors in terms of detail that it’s able to capture. There are a few limitations – for example the phone isn’t able to bring out details in areas where the sensor just doesn’t see anything, particularly scenes with brighter objects requiring a wider dynamic range in the capture is where things hit a snag, although details are still excellent even in these scenarios.

The biggest disappointment was the wide-angle camera. Here it’s not only that Apple’s night mode photography isn’t available for this unit, but the module doesn’t even compete against phones without their respective night modes enabled. So the iPhone 11 series is utterly put to shame when they do enable it. I do hope Apple is able to iterate on its processing for this unit as currently it’s just outright terrible and not competitive.

I do have a feeling that we’ll be seeing further updates and improvements from Apple in improving the various aspect of the camera. Already I did notice that iOS13.2 fixes exposures longer than 3 seconds for the night mode, and there’s of course the question of how Deep Fusion behaves in low-light scenarios where the night mode doesn’t kick in.

    FYI, while al other new models are rated IP68, the pro’s are listed as having a maximum submerged depth of 4 meters for 30 minutes, vs 2 for the non-pro model. Your spec comparison on the first page lists them all at 2 meters.

    I think my perfect phone right now would be all of the 11 Pro's hardware shoved into the body the size of the iPhone 5, but obviously with the full-front screen. Unfortunately there doesn't appear to be much will amongst any of the premium phone manufacturers in wanting stuff to be smaller these days :(
    iPhone 11 Pro Nano anyone?
  • p1esk - Wednesday, October 16, 2019 - link

    Yes, I’d love a smaller iPhone.
  • nirolf - Thursday, October 17, 2019 - link

    Smaller and lighter! I'm holding on to my 7 until they release something similar in size.
  • Eliadbu - Wednesday, October 16, 2019 - link

    no iphone 11 pro but *rumors* say there is new Iphone SE2 for 399$ with a13 and 3GB of ram
    but I doubt it will be full front screen or AMOLED screen. but imo it will sell like hot buns from the oven. there is huge market for budget phone and a new iphone SE with same SOC as flagship, plenty of ram and IOS for 399$ is really compelling I know many people just lurk for used\old gen Iphones just so they can get Iphone for low price, this phone will draw the masses.
  • MamiyaOtaru - Friday, October 18, 2019 - link

    unfortunately the rumors seem to paint Apple as being more interested in the price aspect than the size aspect. Like it will be more modern innards in an iphone 8 body. Which misses a great deal about what I liked in the original SE.
  • Eliadbu - Saturday, October 19, 2019 - link

    I see your point, but you need to understand the current market. Iphone sales and other premium flagship are declining while budget phones are on the rise especially in certain markets where most people can't afford expensive phone so they look for the best phone they can get at the budget lineup. Now there are cheaper options than 399$ but arguably no better options. Apple knows it loses huge market share by not creating option for that price point. Also if they put a13 in that phone it will be overkill. They should either use older chips that cost less now like the a12 or a11 which both are more than enough for budget phones, or they can use smaller more power efficient a13 that would cost less and put the money on newer display design or more cameras which will be better selling point than using a13, imo.

    Guess you got it now with the 12 and mini!

    I believe it's time for AT to really upgrade its website to be able to make use of the full width of modern displays. It's excruciating to go through these reviews and click through each camera sample without being able to compare things side-by-side. Even the performance graphs are so cramped. I hope an upgrade is on the way...

    "Nevertheless, I do question why Apple decided to be so aggressive in terms of power this generation."

    I imagine it has something to do with the much bigger battery they put into the phone; current draw wearing down the battery isn't as much of a concern when it is larger. The little cores are far more impressive this year with roughly A73-75 levels of performance at much better efficiency. They seemed to have listened to users by making the phone a bit chunkier in exchange for a bigger battery.

    The inefficient modem is still a sore spot this year which should hopefully be addressed next year with the inclusion of Qualcomm parts and IP. More importantly, the impact of a closed ecosystem with management who care more about profit than users is being felt by real customers in places like Hong Kong or vendors like EPIC who have avenues other than the official OS vendor sponsored app store on Android. Regulators should force Apple to offer an open store API for third parties to set up store fronts so that customers could have more choice based on pricing, quality, and reputation.
