I agree, an ordinary cute butterfly with a strong magnification can seem like a creepy monster. And if you remember that butterflies also bite ...)))

At first, I also did not accept the term "macro" to the microcosm. After all, everything small is micro. From here we have a microscope. .

On the other hand, macro is an increase. The lens conventionally magnifies the object to 1:1 or more. Maybe from here it is called a macro lens. And that's why shooting with it is called macro. Then the name of the macro photos is logical))

If I understood correctly the term macro refers to the photograph, not the subject being photographed.

It turns out that so.
