809. 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.

Unlike the allowance for monochrome, most of the allowed “limitations of the medium” involve non-“light”-related aspects.
