In macro photography also known as close-up photography, the image projected on the digital sensor is the same size as the object being photographed, thus providing a larger and clearer image of even the tiniest object. The lenses used for this type of photography usually have a long barrel for close focusing and are referred to as macro lens. The specialized optics included in these lenses allows them to focus down to magnifications as close as 1:1 without requiring any other device and provide a 100% life-size of the object photographed.
