I don’t think that’s what they’re saying. AP is quoted in the guardian as follows:
Associated Press said that according to its “news values and principles”, minor edits to photos including cropping, toning and colour adjustment are “acceptable when necessary for clear and accurate reproduction and should maintain the authentic nature of the photograph”
It added that “changes in density, contrast, color and saturation levels that substantially alter the original scene are not acceptable. Backgrounds should not be digitally blurred or eliminated by burning down or by aggressive toning. The removal of ‘red eye’ from photographs is not permissible.”
