In the earliest stages of photography, developments in optics and light-sensitive materials made photography more possible.
1. Optics: The advancements in lens technology were crucial for focusing light onto the light-sensitive material, ensuring clearer and sharper images. These improvements allowed for better image projection and capturing of more light.
2. Light-sensitive materials: Initially, silver salts were used on plates or paper, which would darken when exposed to light. However, these materials were not very sensitive and required long exposure times. The development of more sensitive materials, such as daguerreotype plates and later dry plates, improved the efficiency of capturing images and reduced the exposure time required.
3. Chemical processes: The discovery and understanding of chemical processes, such as sensitizing silver salts and developing and fixing techniques, played a significant role in making photography more accessible and practical. These processes allowed for the production of permanent and reproducible images.
Combining advancements in optics, light-sensitive materials, and chemical processes ultimately made photography more feasible, leading to the development of different photographic techniques and processes such as the daguerreotype, calotype, and wet plate collodion.
