Lizard (detail)

What is a macro shot?
Is it a picture taken with a macro lens, projecting a 1:1 size image on a film?
Or must it just present a bigger-than-life reality, and enlarge it in such a way that you discover details and a beauty not to be seen with the naked eye?

If you adhere to the former definition, this is no macro shot: it’s a detail of this picture.
I strongly doubt, however, if that formalistic approach still holds in the age of digital photography: there used to be macro shots before “macro lenses” even existed, and there will be without them.
