Ambrotype Photographs are photographic images created using glass negatives.
Brief history and description
Ambrotype photographs were invented by Frederick Scott Archer, who was originally from either Bishop's Stortford or Hertford in the UK, (although James Ambrose Cutting first came up with the term "ambrotype" in 1854).
Ambrotype photographs are typically shiny in appearance, and are created as negatives on a piece of glass and then transfered to a black background.
Ambrotypes were incredibly popular during the mid to late 1800s, however, it is not uncommon to find photographers and/or artists who still practice ambrotype photography today.
Guide for collectors
Ambrotypes of historical and notable individuals are considered to be the most rare and valuable.
Given the delicacy of an ambrotype photograph, it is incredibly rare to find an ambrotype without any wear and tear. Because of this, restoration of an ambrotype is not recommended, as restoring an ambrotype will decrease its value.
For more information regarding Ambrotypes, visit the official website of the Royal Photograph Society, as well as the official website for The Daguerreian Society.
