Hi,
after getting the tonemapper finally running (see other thread) I struggle to grasp what it is doing. Even if exposure and gamma are set to 1.0f it modifies the image. You can test that in the denoiser example from the sdk. Line 546 and 547. Just set exposure and gamma to 1.0f. Or comment the lines.
I would expect it to not change the “original” image, but it does get darker here.
I’m also unable to invert the tonemapping. One stage with gamma and a following stage with 1/gamma does not result in the orginal image.
Is this a bug?
Cheers,
Nico
