A filmmaker and colorist who tested the video capabilities of the iPhone XS in low light said that the results were so good that it was perhaps best to simply leave the application of the iPhone. camera act in its own way rather than using manual commands with FiLMiC Pro …

Richard Lackey said camera improvements should not be underestimated.
[Apple,] my head turns my head trying to figure out what kind of voodoo you shoot in this phone […] The iPhone XS Max, XS and XR camera systems seem to generate images that exceed the sum of its parts.Even though it may be "just" of an "S" year, the importance and impact of Apple's clear focus on sophisticated image processing should not be underestimated. real-time computing. […]
With the iPhone XS Max, I was able to capture a sharp video in very low light conditions. Not only was it clean, but it contained more information about the colors in the darker areas of the image than any iPhone of the previous generation with which I shot.
Low light image processing
He added that the dynamic mapping of sounds used seems to be particularly sophisticated.
Judging by the behavior of the camera under conditions of intense and normal brightness, it appears that the luminance values recorded are not purely determined by a fixed gain value (ISO), nor by a fixed gamma transformation, as would be the case with I will call it "stupid") camera.
Something else is at stake, dynamic, evolving according to a combination of variables related to a real-time analysis of the scene. It may even make separate localized adjustments to different parts of the image, which would be extremely impressive if it were true.
Noise reduction too. He wrote that he could normally locate artifacts resulting from this, but that he could not in this case.
Whatever combination of spatial and temporal analyzes is used, it is very very good and probably applied early enough in the signal chain. I also do not think it is applied globally to the whole picture. It seems that this could be located only in the areas of the image that will benefit. […]
What surprises me the most is the dimly lit image areas that I would normally expect to see a lack of detail and texture, details and a correct texture. Go understand. Not quite sure how they are doing.
The bottom line
But most striking of all, a professional filmmaker actually thinks that the camera could better choose the settings than it would do it itself.
I do not see many reasons to shoot with gamma profiles flat or log. In fact, I think the best results could very well come from an iPhone left to itself. It may be more efficient to maximize the recorded dynamic range with its own intelligent sound mapping than can be done manually.
If I still did not use a standalone camera for a scheduled shoot, it might be enough to change my mind not to switch to the iPhone XS. It certainly seems that the improvements are more spectacular than they have appeared.
Watch the video below to judge for yourself. It starts with a graduated version, followed by direct footage from the camera.
