In a PC/Windows environment, with a monitor correctly calibrated, a right gamma correction for Yafray renders would be 2.2. Is that actually true?
Let me elaborate a bit. Yafray default gamma settings is equal to 1, which means no gamma correction at all.
BTW, Blender internal default setting is “gamma correction” always on.
But according with this http://www.gijsdezwart.nl/tutorials.php, YafRay gamma correction must be actually equal to 2.2 if you want to work in linear workflow with Yafray, like Blender does.
Therefore, in a PC/Windows environment, with a monitor correctly calibrated, a right gamma correction for Yafray renders would be 2.2. Is that actually true?
I’ve doing some test with gamma correction enabled. All I can say is that the predicted results have become true: lighting more powerful, more range for shadows, light attenuation more natural!
I think you are correct I usually just turn up the exposure in the yafray panel it seems to compensate for the different way yafray handles lamp intensity. but I see with the gamma set to 2.2 the exposure adjustment seems to be less to get a nice looking render.
thanks for the tip.
I’m no expert on gamma correction so
I am unable to give you an answer.
Here is a good explanation of gamma correction.

Macintosh is 1.8
PC 2.5

At this time it is my opinion that
a good safe setting is 2.0.
