Questions about the term “undoctored” are here

  • 1201. What’s the point of P2?

    In light of Characteristic #2 of trusted photographs, P2 ensures that every TTG-qualified photograph remains “undoctored.”

  • 1202. So TTG photos have to be “undoctored” but they do not have to be “unmanipulated” or “unaltered”?

    That is correct. The distinction is explained in the Key.

  • 1203. Can photographers use their own definitions of “undoctored” when making TTG photographs?

    Photographers can define any terms any way they want, but if a photo doesn’t fully meet the Trust Test it is disqualified from TTG.

  • 1204. Why does “A” in P2 single out lighting effects, non-optical bokeh, and post-exposure perspective correction?

    Because those are the three TTG-disqualifying manipulations that are most likely to be specified on smartphones before the photograph is recorded.

    The manipulations listed in “C” of P2, on the other hand, are usually specified after the photo has been recorded.

  • 1205. Does the term “record” in P2 refer to anything more than “what the camera recorded”?

    No.

    But that doesn’t mean the term is insignificant; see this viewpoint page.

  • 1206. Why does TTG say the list of Allowable Changes (linked to P2) reflects “a worldwide consensus”?

    Because that list includes all 7 of the kinds of changes that are built in to billions of devices and embraced by billions of users around the world.

    By building in those actions, smartphone makers have established a worldwide consensus (see #800) about “doctoring a photograph.”

  • 1207. Why are changes #1, 2, and 3 on the “Allowable Changes” list (linked to P2) if they aren’t built in to billions of smartphones?

    #1, 2, and 3 are there because they are central to photography.

    (The other 7 changes on the list are discussed in #800)

  • 1208. And P2’s “Allowable Changes” list also applies to “the most-widely trusted photographs in the free world”?

    Yes, very few of “the most widely trusted photographs in the world” undergo changes that are not on TTG’s list of Allowable Changes.

    Just about every photo put before the wider public — including newsphotos — undergoes at least one or two of TTG’s Allowable Changes.
