Close-up or macro photography is a specialized form of underwater photography where the camera lens is positioned very close to a subject, or is able to zoom into the subject, to record a relatively large image in high magnification of the original subject.

My guide and I saw the croc on the surface, basking in the sun, laying on the papyrus grass. It was a Nile crocodile about five meters long and agitated by our invasion of its space. It moved lethargically and got into the water. We followed it, as it swam against the current.
