“You can manipulate a photo any way you want. But you can't manipulate a photo any way you want and expect viewers to trust it.”
Why does TTG rule out several popular manipulations?
Because with many manipulations, it is impossible to set limits that keep the manipulation from being carried to untrustworthy extremes.
• That lack of limits is fine for unlabeled photos.
• But if “extremely untrustworthy” photographs could qualify for the TTG label, then the TTG label would be worthless.
