From Wikipedia, the free encyclopedia
Macro photography refers to close-up photography; the classical definition that the image projected on the "film plane" (i.e film or a digital sensor)is the same size as the subject. On 35 mm film (for example), the lens must have the abilityto focus on an area at least as small as 24×36 mm, as this is the size of the image on the film. This is known as "life-size magnification" or simply 1:1.
In recent years, the term macro has been used in marketing material to mean being able to focus on a subject close enough so that when a regular 4×6 inch (102×152 mm) print is made, the image is life-size or larger. This requires a magnification ratio of only approximately 1:4, more easily attainable by lens makers.
