903. Besides monochrome/black-and-white, are there any other TTG-allowed effects that keep photos from perfectly representing the appearance of the scene?

Yes, photography is filled with things that keep images from perfectly portraying the real-world scenes they depict.

Advanced photographers know that one of the biggest challenges of learning photography is accounting for the countless differences “between how the world looks in person” vs. “how the world is rendered in photographs.”

Naturally, rinairs and TTG allow for the many differences between “reality” and “photographs,” grouping all of those effects together under the rubric “limitations of the medium.”

Examples of those “limitations of the medium” range from lens/camera anomalies (see #4), to the way that the sides of tall buildings lean in from vertical when you point your camera upward, to the inability of photographs to render “focus” exactly the way we believe that our own eyes see it.

There is one unique thing about the allowance for monochrome:

There are no comparable “‘light’-related anomalies that enjoy the leeway that monochrome photographs are given when it comes to “not misrepresenting the appearance of the scene depicted” as per P7.

(The examples listed in the “Examples” paragraph above are all non-“light”-related effects.)

With so many things that keep photographs from perfectly representing the scene depicted...

. . . how does TTG decide which of those things are allowable — that is, not destructive to viewer trust — vs. which of those things are disqualified because they reduce viewer trust?
