Albumen print
The albumen print, also called albumen silver print, was published in January 1847 by Louis Désiré Blanquart-Evrard, and was the first commercially exploitable method of producing a photographic print on a paper base from a negative. It used the albumen found in egg whites to bind the photographic chemicals to the paper and became the dominant form of photographic positives from 1855 to the start of the 20th century, with a peak in the 1860-90 period.

The carte de visite, abbreviated CdV, was a type of small photograph which was patented in Paris by photographer André Adolphe Eugène Disdéri in 1854, although first used by Louis Dodero. Each photograph was the size of a visiting card, and such photograph cards were commonly traded among friends and visitors in the 1860s. Albums for the collection and display of cards became a common fixture in Victorian parlors. The immense popularity of these card photographs led to the publication and collection of photographs of prominent persons. (...) Wikipedia
The ambrotype (from Ancient Greek: ἀμβροτός — “immortal”, and τύπος — “impression”) also known as a collodion positive in the UK, is a positive photograph on glass made by a variant of the wet plate collodion process. Like a print on paper, it is viewed by reflected light. Like the daguerreotype, which it replaced, and like the prints produced by a Polaroid camera, each is a unique original that could only be duplicated by using a camera to copy it. (...) Wikipedia
Collotype is a dichromate-based photographic process invented by Alphonse Poitevin in 1855, from which beautiful tonal images can be reproduced without the need for halftone screens. In Poitevin's process, a lithographic stone was coated with a light sensitive colloid and after thorough drying, exposed to a continuous tone negative. After exposure, the coating was washed under clean, running water and left to dry. (...) Wikipedia
A tintype, also known as a melainotype or ferrotype, is a photograph made by creating a direct positive on a thin sheet of metal coated with a dark lacquer or enamel and used as the support for the photographic emulsion. Tintypes enjoyed their widest use during the 1860s and 1870s, but lesser use of the medium persisted into the early 20th century and it has been revived as a novelty and fine art form in the 21st.
