Render 1: Render View
Render 2: Command Line
It seems there is a gamma flucuation between Render View (or Batch Render) and Command-line rendering. I've played with Color Management a bit and also read the ongoing thread, but I'm not pleased and have disabled it. I did not enable it before experiencing this problem. My goal is to have the Command-line output match that of the Render View.
My setup is a simple interior scene, Portal lights, Physical sun and sky, Photographic Exposure (gamma set to 2.2), and gamma correction nodes on textures (.454). Frame Buffer gamma is set to 1 and I'm rendering in 8-bit. When I render in 32-bit, I can at least adjust the gamma in post, but the output still does not match the Render View. I checked the Hypershade > Display > Color Management panel and both are set to linear, with Exposure and Contrast at 0.
