It is different from micro-photography in that micro-photography enlarges extraordinarily small things that can't normally be seen with the naked eye.
The term "Macro" photography refers to reproductions beyond life-size reproductions The magnification ratio is generally accepted as 1:1 to 22:1. The term magnification or reproduction ratio is simply defined as the image-on-film size X to the actual subject size Y and is represented in the form of X:Y. For a magnification ratio of 1:2, the subject size would be two times larger than the captured image on the actual film or the image on film is a tenth of the actual size. In a 1:1 magnification ratio, the capture image would be the exact size as the actual subject, hence the term life-size. For larger than life-size magnifications, say 10 times the actual size, the magnification ratio would be 10:1...
