KK: /ˈfoʊtəˌɡrævjʊr/
A method of printing that uses a plate etched with a photographic image to create high-quality images, often used in art and photography.
The artist used photogravure to reproduce his work with stunning detail.
Photogravure → It is formed from "photo-" (from Greek "phōtos", meaning light) and "gravure" (from French "gravure", meaning engraving). The word refers to a printing process that uses light to create an engraved image.
Think of 'light' ('photo-') being used to create an 'engraved' image ('gravure') — that's how photogravure works.
