| 释义 |
An Albertype is a picture printed from a kind of gelatine-coated plate produced by means of a photographic negative.[1] The process was invented by Josef Albert in 1869.[2][3] The technique is similar to collotype, but substitutes the gel plate for the lithographic stone used in collotype.[2] Heliotype, invented in 1871 by Edwards, is another similar process.[2] References1. ^{{Cite book|title=The Photographic News: A Weekly Record of the Progress of Photography, Volumes 31-32|last=|first=|publisher=|year=1887|isbn=|location=|pages=187}} {{photography-stub}}2. ^1 2 {{Cite book|title=Mapping the Spectrum: Techniques of Visual Representation in Research and Teaching|last=Hentschel|first=Klaus|publisher=Oxford University Press|year=2002|isbn=9780198509530|location=|pages=156}} 3. ^{{Cite book|title=Encyclopedia of Nineteenth-Century Photography|last=Hannavy|first=John|publisher=Routledge|year=2013|isbn=9780415972352|location=|pages=}} 2 : Photographic processes dating from the 19th century|1869 establishments |
