A method comprising applying a conversion function to first RGB picture data in a color gamut and corresponding to a first non-linear domain to obtain second RGB picture data in the same color gamut in a linear domain, said conversion function being a combination () of a first and a second function, the first function being a linear function defined between zero and a second inflexion point the slope of which depending on a steepness value and the second function being a part of a linear to first non-linear domain transfer function defined from the second inflexion point, the second inflexion point being computed () in the first non-linear domain from a first inflexion point obtained () in the linear domain, the steepness value being computed () from the first and second inflexion points.
