The Calotype process, invented by William Henry Fox Talbot, used a paper negative to create positive prints.

The Daguerreotype process, developed by Louis Daguerre, utilized a silver-plated copper plate as the light-sensitive surface.

The Daguerreotype process resulted in a unique positive image on a silver-plated copper plate.

The Ambrotype process was more economical compared to the Daguerreotype process due to the use of glass instead of silver-plated copper plates.

The Wet collodion process, also known as the Collodion process, utilized a collodion-coated glass plate as the negative.

The Wet collodion process required careful preparation and handling of the collodion-coated glass plates, making it a technically demanding process.

The Tintype process, also known as the Ferrotype process, utilized tin-coated iron plates to create positive images.

The Tintype process was more affordable than other early photographic processes due to the use of inexpensive tin-coated iron plates.

The Ambrotype process gained popularity for portrait photography due to its relatively low cost and ability to produce sharp and detailed images.

The Calotype process required long exposure times, making it challenging to capture moving subjects or scenes with insufficient light.

The Albumen print process allowed for the production of multiple positive prints from a single negative, making it a popular choice for commercial and artistic photography.

The Albumen print process utilized albumen, a protein derived from egg whites, as the light-sensitive material.

The Cyanotype process, also known as the Blueprint process, was widely used for landscape and architectural photography due to its simplicity and ability to produce blue-tinted images.

The Cyanotype process utilized a mixture of potassium ferricyanide and ferric ammonium citrate as the light-sensitive material.

The Gum bichromate process produced distinctive reddish-brown images due to the use of gum arabic and potassium bichromate as the light-sensitive materials.
