Macro photography is close-range photography for high detail but does not require the help of an optical magnifier such as a microscope. Macro photography usually has a 1: 1 ratio of the size of the image that is produced the same size as the original object. For example, in 35 mm film, the lens should be able to focus on an area as small as 24 × 36 mm, ie the size of the image on the film.
