Both cameras have bad dynamic range and look bad.
Dear nofilmschool please put the price in the article.
I haven't shot on an inter-frame codec in a long time, but back when I used to shoot on a canon dslr, and I know this may seem weird, before color grading I would convert all of the clips into pro res 422. This significantly removed the banding I would get in the gradient shadows.
Also I've used the noise removal software in Resolve to soften banding on iphone clips. The motion noise removal in resolve blends together like colors and significantly takes care of this problem.
This answer isn't supported by science or anything but it has helped me in the past.
Best of luck.
What a game changer.
Most of your favorite films weren't shot in 4k but instead 2.8k on the Arri Alexa.
This is great! Thank you.
