 Paradoxically, when upsampling (scaling up) an image, the result processed in the "wrong" gamma-enabled space tends to be more aesthetically pleasing.This is because upscaling filters are tuned to minimize the ringing artifacts in a linear space, but human perception is non-linear and better approximated by gamma.An alternative way to trim the artifacts is using a sigmoidal light transfer function, a technique pioneered by GIMP's LoHalo filter and later adopted by madVR.
