Macro photography is close-up photography. The classical definition is that the image projected on the “film plane” (i.e., film or a digital sensor) is close to the same size as the subject. 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 6×4 inch (15×10 cm) print is made, the image is life-size or larger. With 35mm film this requires a magnification ratio of only approximately 1:4, which demands a lower lens quality than 1:1. With digital cameras the actual image size is rarely stated, so that the magnification ratio is largely irrelevant; cameras instead advertise their closest focusing distance. Macroscopy competes with the digital microscope where a small camera tube can be attached directly to a computer, usually via USB port. Macroscopy also competes with photomicroscopy, and it is much less expensive to achieve high quality images. However, high magnification images are more diffi
