Filmmaker says iPhone XS sensor and image processing makes
low-light video ‘voodoo’ good

A filmmaker and colorist who put the iPhone XS low-light video capabilities to the test says that the results are so good that it may be better to simply let the camera app do its own thing than to use flat or gamma log in something like FiLMiC Pro …

Richard Lackey said that the camera improvements should not be underestimated.

[Apple,] you’ve got my head spinning trying to
figure out what kind of voodoo you’re pulling off
in this phone […] The iPhone XS Max, XS and XR camera
system seems to generate images that are beyond the sum of its parts.

LOW-LIGHT IMAGE-PROCESSING

He said that the dynamic tone mapping employed appears to be particularly sophisticated.

Judging from the behavior of the camera in bright
and normal lighting conditions, it appears that
the luminance values recorded are not purely determined
by a fixed gain value (ISO), or fixed gamma transform
as would be the case with a “traditional”
(I’ll call it “dumb”) camera.

The noise-reduction likewise. He wrote that he can normally spot artefacts resulting from this, but he couldn’t in this case.

THE BOTTOM-LINE

But most tellingly of all, a professional filmmaker actually thinks that the camera might make a better job with its own settings that choosing his own base profile.
下略

If I didn’t still use a standalone camera for any planned shooting, this might be enough to change my mind about not upgrading to the iPhone XS. It certainly seems that the improvements are more dramatic than they first appeared.
