Kalotypia, also known as calotype, is an early photographic process developed by Henry Fox Talbot in the 1840s.

This capability of reproducible imagery marked a major shift from the single, non-reproducible images of earlier methods.
The term kalotypia derives from Greek roots meaning “beautiful impression.” The process was among the first
