The invention relates to a method of modifying the appearance attributes of digital images comprising: defining in a first channel of a color corrector a first set of appearance attribute corrections to be applied to the images; determining a first set of appearance attribute correction parameters corresponding to the first set of appearance attribute corrections; in the first channel of the color corrector defining at least one further set of appearance attribute corrections to be applied to the images; determining a set of appearance attribute correction parameters corresponding to the or each of the further sets of appearance attribute corrections; and combining each of the sets of appearance attribute correction parameters into a single set of appearance attribute correction parameters. The invention also relates to a method where the channel is implemented in software and to apparatus and software for carrying out the methods.
