The iPhone XS's camera specs were virtually identical to those of the iPhone X, but the dual-camera system offered subtle improvements over its predecessor. While it stuck with a wide-angle lens and a 2X telephoto lens, they had larger and faster sensors, bigger pixels, and an improved image signal processor (ISP).
The iPhone XS was the first generation to support Smart HDR. It rapidly fires off multiple shots unseen to the user, applying machine learning through the Neural Engine to keep each image's best portions. The result is a single photo with a wider spectrum of light and dark areas than any single picture could have provided. All of this happens in the background at close to real-time, taking a few seconds at most.
The handset was also the first to include bokeh and depth controls for Portrait Mode. After taking a Portrait Mode shot, you can adjust the background-blur level and apply portrait effects like studio light and contour light.
The primary wide-angle camera had a 20% larger pixel depth that provided better light sensitivity for low-lit shots.
The following generation, Apple added Night Mode for much better shots in poorly lit environments. Similar to Smart HDR, it takes multiple photos and uses machine learning to create a single image. Night Mode doesn't work on the iPhone XS.
The iPhone XS's rear cameras are both 12MP. The wide lens has ƒ/1.8 aperture, while the telephoto lens is ƒ/2.4. It can record video in up to 4K resolution at up to 60fps.
The TrueDepth front-facing camera is a single 7MP lens with ƒ/2.2 aperture. It supports HDR and Portrait Mode with bokeh and depth control.
Initially, the iPhone XS sparked a minor controversy dubbed "Beautygate," where customers noticed a strange beauty-filter type of appearance in their selfies. The front camera was over-applying noise reduction to Smart HDR shots, creating the appearance of excessively soft skin. Apple eventually fixed this in a software update.
"In comparing the iPhone XS to last year's iPhone X, the main upgrade is the camera system. Specifically, the new model excels in low-light photos, performing in ways last year's flagship model simply could not"Immediately upon testing the camera in dark and dim settings, we found that its ability to capture high quality images in otherwise poor conditions was greatly improved.
"We did find that color accuracy could be sacrificed in these lower light images — one photo captured at an outdoor concert gave the ambient lighting a greenish hue that was not visible to the naked eye. However, the results still wowed. After sending one image to a friend, their first reaction was, 'Wow, you shot that on a phone?'
This impressive low light performance is made possible by a number of significant changes to the camera system, including an image sensor that is somehow 30 percent larger than last year's model, despite the phone itself being the same thickness. The camera also captures 1.4m pixels, and features a new Smart HDR mode that combines a number of exposures into one.
"Apple has also reduced shutter lag and increased the number of focus pixels over the iPhone X, with a revamped system powered by the handset's beefy A12 processor. And the improved lenses feature dual optical image stabilization, meaning shots are less blurry in both photos and video.
