Hi guys,
I am kind of confused about the use of the tone mapper. It looks like a default color correction and don’t really understand why it is default enabled and what the use of it is.
How can I turn it off and just look at real colors? black = black, white = white?
It’s there to emulate the fact that our eyes can see a much wider range of exposures at once than our displays can produce. Without it there would be a lot of detail being lost, either from clipping, not having enough brightness, or not having enough different values. Many of the best looking games out right now take advantage of tone mapping to great success. It’s kind of a necessity when you get into physically based lighting and realistic lighting setups.
There’s a really good video on the tone mapper on Epics YouTube channel. It is horrible if you don’t care at all about physically based lighting and rendering, but even Pixar who embraces stylized and cartoony visuals embraces things like tone mapping and PBR.
Hopefully in the near future with HDR displays tone mapping can be a bit less aggressive, and let our eyes do the work instead.
