What about the other three requirements — P7, P8, and P9?

P1 through P6 — “the six requirements that expressly spell out what can and cannot be done to TTG photographs” — are explored here.

The last three requirements of the Trust Test focus on viewers’ expectations and perceptions:

• P7 plays a “cleanup” role (see #1702) and is about avoiding misrepresentation.

• P8 is the “loophole closer” (see #1802) and is about avoiding deception.

• P9 is the “handoff” requirement (see #1902) and is about avoiding mistrust of the source.
