Through the Looking Glass
Glass negatives were a boon to photography when they were first introduced in the 1860s. But it was with the invention of the gelatin dry-plate glass negative, coming on the market in 1871, that the medium really established itself as an alternative to the messy wet-plate process or the unreliability of early paper negatives. A thin sheet of glass covered with a silver salts emulsion was so much easier to use than the wet collodian process that it enabled early photographers such as William Henry Jackson and Ben Wittick to traverse the West, capturing some of their later iconic images.
