[Algorithms] Color balance





Hi list,

Our artists would like to have the color balance processing effect
inside the engine function exactly as the one in Photoshop. I looked
at the Gimp's formula, but even the Gimp's developers seem to agree
that it is somewhat strange and that it doesn't match the one in
Photoshop. Finding the original PS's formula somehow escapes all my
googling skills. :(

Does anyone happen to have any references to this?

Thanks,
Alen
