![]() ![]() For example, when producing a 6×4-inch (15×10-cm) print using 35 format (36×24 mm) film or sensor, a life-size result is possible with a lens having only a 1:4 reproduction ratio. Īpart from technical photography and film-based processes, where the size of the image on the negative or image sensor is the subject of discussion, the finished print or on-screen image more commonly lends a photograph its macro status. Likewise, a macro lens is classically a lens capable of reproduction ratios of at least 1:1, although it often refers to any lens with a large reproduction ratio, despite rarely exceeding 1:1. The ratio of the subject size on the film plane (or sensor plane) to the actual subject size is known as the reproduction ratio. In some senses, however, it refers to a finished photograph of a subject that is greater than life size. īy the original definition, a macro photograph is one in which the size of the subject on the negative or image sensor is life size or greater. Macro photography (or photomacrography or macrography, and sometimes macrophotography ) is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life size (though macrophotography also refers to the art of making very large photographs).
