DaVinci Resolve also supports OpenEXR format with the added magic of LUT.

PNG is popular with some Commercial Application developers, but the exposure and color problems still look 1980's awful in some use-cases.

Even after spending a few grand on seats for a project, one still gets arrogant 3D clown-ware vendors telling people how they should run their pipeline with PNG hot garbage as input.

People should choose EXR more often, and pick a consistent color standard. PNG does not need yet another awful encoding option. =3

What are some "consistent color standards" you'd recommend? Honest question.

Like all complex questions, the answer is it depends on the target project and or Display.

A very basic rec.709 workflow tutorial:

The Andreas Dürr LUT pack:

The calibration workflows also depend heavily on what is being rendered, source application(s), and the desired content look. There were some common free packs on github for popular programs at one time. Should still be around someplace... good luck. =3
