Almost any commonly recognized definition of the noun “photograph” will suffice when describing the kinds of images to be held up against the Trust Checklist.
Obviously not everything called a “photograph” as defined by every definition will qualify as TCQ. (That’s the point of having a standard; see #332.)
In other words, many many types of images that are regarded as “photographs” may be disqualified by one or another qualification of the Trust Checklist — but that disqualification by TCQ does not make those images something other than “a photograph” (see #1104).
The point is that TCQ is never involved in any way in the defining, or redefining, of what “a photograph” is.
The Trust Checklist merely checks which images that are called “photographs” have all 9 characteristics of the world’s most-widely trusted photographs.
