Macro photography allows the capture of extreme close-up shots where the subject appears larger than life size. Advances in camera sensors have made macro photography more accessible at lower costs without specialized macro lenses. Macro lenses designed for close-up work have long barrels to focus closely and optimize reproduction ratios, and different focal lengths suit various macro subjects like products, insects, and scenes. Equipment useful for macro photography includes high resolution cameras, dedicated macro lenses ranging from 65mm to 150-200mm, ring flashes, and an inexpensive tripod.
