Dithering problem

[Delizade]

Hi,
I have a problem about denoised rendered image.
What is the problem here? Why 16 bit denoised image has rippled areas?

I added sample images below (Brightness values are increased to emphasize the problem)

Hi,

Ditching PNG entirely is the first step towards a proper imagery.

Quoting this post:

ACES+PNG(8-bpc)+Photoshop is one of the most inexpedient recipes, to avoid at all cost.

A proper EXR (or at least, TIFF) workflow, in a proper compositing software (e.g. Nuke or Fusion) would yield expected results, correctly and hassle-free. ACES is absolutely dispensable.

Worth mentioning about the dithering option in the Octane's Camera Imager. Handy in some situations.
