Definitions for "MACROPHOTOGRAPHY"
Close-up photography in the range of magnification between life-size 1:1 and about ten times 10:1.
Technique of taking larger than life photographs with an ordinary camera lens. The image in the camera will be the same size as the subject, or larger than the subject. If you are shooting a one-half inch worm you will have an image of the worm that is one-half inch long measured on on the slide or negative. That is what is meant by a scale of 1:1, one to one, the size of the image is equal to the size of the subject. See: Photomicrography.
Photography of a subject where the image is recorded in the same or larger than actual size.
