Different image gamma between 2.77 and 2.78. #216

Render output image in 2.78 using same configuration is much darker and has lower gamma. In both cases I've sRGB enabled.

left: 2.77 right: 2.78 Gamma difference

Since couple of nightlies the 'sRGB' option has been removed from Render -> System -> Exporter. Now the exporter uses the blender setting: Scene -> Color Management -> Display Device.

Does setting the correct value in Color Management produce the correct gamma?

Ok, I figured it out. For some reason 2.78 defaulted to "Color Mapping" mode without Gamma. So whenever I opened 2.77, Gamma value (which is set to 2.2 as default) was applied. In 2.78 it wasn't.

Color Mapping

Thanks for info about sRGB. I didn't know it was moved to Color Management. Make sense. For my previous tests I just enabled it manually.

As for the issue itself. I cannot reproduce it after saving file with Color Mapping & Gamma mode. Both versions output render with the same gamma value now.

Closing.
