A small image that is taken using a microscope or special equipment, which needs to be enlarged to be seen clearly.

Microphotograph → It is formed from "micro-" (from Greek "mikros", meaning small) and "photograph" (from Greek "photos", meaning light, and "grapho", meaning to write). The word refers to a photograph taken of something very small, often using a microscope.
Think of 'small' ('micro-') and 'writing with light' ('photograph') to remember that a microphotograph is a picture of something tiny.
