What is a glass plate negative?
Glass plate negatives are photographic negatives created by coating a glass plate with a light-sensitive emulsion. These were commonly used in the 19th and early 20th centuries for capturing images in photography. The Wet Plate Collodion Process (1850s–1880s) was introduced first which produced very sharp detailed images and required photographers to carry portable darkrooms in the field. Later the Dry Plate Process (1870s–1920s) was invented making these plates easier to store and developed later, making photography more convenient.
These two processes produced high image quality and detail; and were stable and long-lasting if stored properly. A major disadvantage was the weight of the glass negatives and how fragile they were. Eventually celluloid film replaced these glass negatives which was easier to use. Glass plate negatives will always be important to the history of photography because of their exceptional archival quality and exceptional image resolution.
Mills Glass Plate Negatives Collection
Photographer Lewis S. Mills traveled around Connecticut to capture images of life as it existed around the turn of the century. Sadly, time has erased many of these historic buildings and homes.
