Clamp with care

Blender Cycles clamp setting is a saviour in hard to resolve fireflies, besides a myriad of other methods. Usage of clamp should be taken with care though, as clamping does not only clamp the high values of the mischiveous fireflies, as it also clamps the good brightness of the scene. Below, you can find a comparison between two renders with different clamp settings, with noticeably duller looks on the clamped one.
