I see many (most) of the pictures in macro category are more than the standard definition of macro photography. Having a magnification of 1:1. Macro and exreme macro (which requires multiple lenses of is a product that is more than a lense and a set of extension tubes, should be separate. The reason for this is while it is possible to do macro on live animals, extreme macro most often employs focus stacking. Where numerous images are taken and blended together. This in almost impossible to do on a live or non refrigerated animal and starts becoming akin to still life, as the subject can't move, or the shot is blown. Some will argue otherwise but find me a wasp that will be 100 percent still for 75 shots. As a result, I think two categories are warranted.
