Macro Photography Fundamentals

True macro photography reproduces a subject at 1:1 magnification—the image on the sensor is the same size as the object in real life. A honeybee is about 15mm long; at 1:1, it fills 15mm of your sensor. Dedicated macro lenses (60mm, 90mm, 100mm, or 105mm) achieve this natively. Extension tubes or close-up diopters can adapt non-macro lenses for close-up work at lower cost. At macro distances, the rules of photography change: depth of field shrinks to millimeters, camera shake is magnified, and ambient light often becomes insufficient.
