Yeh, this was something of an it's-about-time-I-posted-an-image render; a bit contrived, perhaps. The plane: yeh, the guy could have just been enjoying the view but I thought I'd give him something more definitive to look at. And, yep, I see I've over-shopped the guy with negative contrast (probably comes from having a fear of replicating the copy-paste and can't-be-bothered-to-blend-it-in examples I've seen at R elsewhere). The grass: hmm, "can do better" must go on my report.
