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.

    Try 4.4Ghz Core2Duo E8600 and Ryzen 3600x in SuperPI 1M.
    You will see E8600 is faster by 2 secs, makes you wonder?

    Released in 1995, 13-15 years difference between two processors. E8600 is faster? LOL
    This SPEC need serious overhauling, same as GB that is tuned to Apple SoC. Apple A13 faster than 5GHZ Intel or Ryzen in GB5? LOL, people are seriously retarded nowadays...

    What has superPI got to do with spec2006? Spec2006 is a well respected desktop/workstation benchmark that tests many different algirthms and use case while superPI does 1 specific narrow test.

    As a real world example, I've found my ipad pro 2018 exports RAW files from Adobe lightroom faster than my 2018 6 core mac mini (i7-8700) and a lot faster than my 2017 13" (2xi5) macbook pro (almost 2x faster).

    Laptopmag also had similar findings. https://www.laptopmag.com/reviews/laptops/new-ipad...

    Do you know that Apple pays Adobe for First Party Optimization ? GB also is not an indicative performance.
  • thunng8 - Thursday, October 17, 2019 - link

    So Adobe Lightroom is optimized for Apple and not their largest platform and money earner which has lots of competitors? That’s the silliest comment I’ve seen yet.

    People aren’t ready to believe it because of their PC / X86 bias.

    The writing is on the wall. Objective measurements show that Arm has caught up, and half the people in these comments are making excuses or saying “nuh uh because it doesn’t run Linux”
  • id4andrei - Thursday, October 17, 2019 - link

    Hey joms, spec is an efficiency benchmark. A 5w CPU does not beat an actively cooled 65w one from AMD or Intel. At least in SPECint Apple matches desktop CPUs. That's how you interpret.

    Give credit to Apple and move on.
  • joms_us - Thursday, October 17, 2019 - link

    Problem is, graph is a huge mess, not normalized. For e.g A13 maybe doing 60+ in perf but consuming 5w whereas SD850 is doing 30 perf in a mere 2w. Which one is better?
  • id4andrei - Thursday, October 17, 2019 - link

    From an overall performance standpoint obviously A13. From an efficiency standpoint the 855 equalled the A12. Both are slightly more efficient than A13 from a peak power perspective. In real life, with average workloads, A13 is overall more efficient than both.

    Apple invests a lot in their chips and sets the pace. Come February next year it's up to Qualcomm to narrow the gap.
  • joms_us - Thursday, October 17, 2019 - link

    There you go, efficiency is the key and A13 is not as efficient as you said. Now in realworld comparison, the likes of Note 10 and OP7T are far better and or bang for the buck. Those long perf graphs are really misleading.. time to fix them.
  • id4andrei - Friday, October 18, 2019 - link

    I'm an android user and nothing here is misleading. The A13 is the best SoC.

    One thing to understand is that the iphone here is deliberately actively cooled so that it removes all thermal restraints and show the chip's full capabilities. In real life it would throttle.
