I really didn’t expect the dappled bark to show up in infrared.

Wow.

Do you suppose it has to do with differing light absorption? (I mean, clearly, that's how light works, but different colors being warmer or cooler.) The stop sign didn't really do it, but then metal conducts heat more efficiently than wood (or, I presume, bark).
