Actinography

/ækˌtɪˈnɑɡrəfi/ noun

Definition

A technique for recording or imaging using actinic radiation, particularly in photographic or scientific applications.

Etymology

From Greek aktis (ray) plus graphia (writing or recording), meaning 'writing or recording with rays of light.'

Kelly Says

Before digital cameras, actinography was crucial for early photography—the chemical reactions caused by light rays literally 'wrote' images onto photographic plates.
