History of photography

The development of the dry plate revolutionized photography by eliminating the cumbersome requirements of the earlier wet collodion process, which necessitated preparing and developing plates on-site using a portable darkroom.12
Dry plates made hand-held cameras and snapshots possible due to two primary factors:
- Increased Sensitivity: Gelatin-based dry plates were approximately 60 times more sensitive to light than collodion plates. This increased speed allowed for instantaneous exposures, effectively freeing the camera from the need for a tripod.2
- Convenience and Portability: Because these plates could be factory-produced, stored until needed, and developed long after exposure, they removed the logistical barriers to outdoor and spontaneous photography.12
These advancements paved the way for the introduction of affordable, small hand-held cameras, most notably the Kodak camera introduced by George Eastman in 1888. This shift democratized the medium, significantly accelerating the growth of amateur photography.2
