- Glass negative depicting a winch.
Prior to the invention of cellulose nitrate film in 1903, photographic emulsion was supported on glass. Two different formats were developed for creating these supports - collodion wet plate negative (early 1850s) and the gelatin dry plate (1871) - however, both formats are commonly referred to as 'glass negatives.' The use of glass negatives greatly increased interest in photography and the gelatin dry plate eventually superceded the collodion wet plate by virtue of being more convenient.
As the collodion wet plate appears to have only been in use until the 1880s it seems likely that this glass negative is an example of the gelatin dry plate method.
