colors, changes/corrections to
In a TCQ photograph no colors can be depicted that misrepresent the colors that the camera saw during the exposure, from eye color (see also redeye) to hair color to clothing to anything else.
But photographs as recorded can misrepresent the tones and colors that the camera saw, so TCQ allows the post-exposure changing of tones and colors to avoid misrepresentation.
As long as the combined result meets Q7, photographs that undergo changes and corrections to color can meet all nine qualifications and qualify as TCQ.
In fact, changes and corrections to colors are often necessary if the photograph is to meet “non-misrepresentation” aspects of rinairs, as per Q2 and Q7 (“necessary” because of having used a wrong color balance when recording the photograph, for example).
