calotype
Rare/TechnicalHistorical/Technical
Definition
Meaning
An early photographic process invented by William Henry Fox Talbot, producing a negative image on paper sensitized with silver iodide, from which positive prints could be made.
The term refers specifically to Talbot's patented process (1841) and the resulting photograph, representing a foundational step in the development of photography, distinct from the contemporaneous daguerreotype.
Linguistics
Semantic Notes
The term is used almost exclusively in historical contexts related to the history of photography, art, and technology. It denotes both the process and the artifact. It is not a generic term for old photographs.
Dialectal Variation
