Resampling simulates physical properties of the light, not subjective perception of the eye.
- jacobolus 9y agoResampling in CIELAB space tends to work better than resampling in gamma-adjusted R′G′B′ space, because at least you never end up averaging two pixels and getting a lightness which is outside the range of input lightnesses, which is what causes the worst artifacts in R′G′B′. A linear space will give a better result, but CIELAB results are usually acceptable.
