Macro photography is magnification of a subject from around 1x life size to 15x. In macro photography, focus stacking can be used to gather more information about a subject. Focus stacking is taking photographs at different distances from a subject, allowing the photographer to gain images of different parts of the subject due to the shallow depth of field as an inherent part of the macro photography process. These images are then combined using software in order to obtain a final image that has the entire subject in focus.
