correction of
In a TTG-labeled photograph, all “light”-related aspects (including brightness, contrast, hue, and saturation) must meet rinairs for non-misrepresentation of the scene that was photographed — regardless of how those “light”-related aspects were originally recorded.
The white balance need not be perfect — it rarely is — but if the “light”-related aspects of a photograph (including white balance) are so far off that they cannot be sufficiently corrected for the final result to meet rinairs (as per P7), the photograph will not qualify for the TTG label.
Note, however, that any photo with uncorrectably bad color can usually* be converted to tonally appropriate monochrome in order to remain eligible to meet P7.
*The exceptions would be photos that were initially recorded with tonal relationships that diverge from the visible light spectrum, such as infrared; see FAQ #1105.
