I was rendering with cycles in Blender 2.8 when I discovered the rendered image looked un-pleasing. As you can see below it has unattractive blothing in the, especially in the skin shadows. I kept trying to turn up the samples, which only helped a little. I realized I was exporting as OpenEXR-multiLayer with 32bit color depth. Below is this image, rendered at 256 samples. (I down-converted it to a 16bit png for the forums.)
I then decided to see what a 16bit png render would look like. Shown below. Same number of samples. The skin tone looks less red and more like a skin tone in the 16bit image. How does 32 bit image rendering supposed t work in cycles? It looks like it adds saturation to the rendered image like a bad Photoshop job. Do I need to produce my materials on an HDR screen? Do I need to change a value to tell blender to render 32 bits instead of rendering 16 bits and then saving it as 32 bits?
