## Early photos took forever
The first photographs required 15 minutes to several hours of exposure time. Subjects had to stay completely still, making portraiture nearly impossible.
## Daguerre's silver plates were faster
Louis Daguerre's daguerreotypes, introduced in 1839, cut exposure time to 3 to 15 minutes using silver plates. They produced sharp, detailed images but couldn't be duplicated.
## Talbot's paper process came close
William Henry Fox Talbot presented his photogenic drawing process to the Royal Society in 1839, just three weeks after Daguerre. His paper-based method was slower and less sharp, but he kept refining it.
## An accidental discovery changed everything
Between September 21 and 23, 1840, Talbot discovered that brief paper exposure left no visible image, but rinsing it in gallic acid revealed a photograph. The accident cut exposure time from minutes to seconds.
## Chemical development was born
Talbot's process mixed light-sensitive paper with a developing solution, drastically reducing exposure time. He called the solution an exciting liquid. Modern film development still uses this developer concept today.
## Herschel added the fixing step
Talbot's early images faded quickly. His friend Sir John Herschel proposed a hyposulfite solution to stop the paper from continuing to be light-sensitive, introducing the fixer step to photography.
## The calotype enabled reproduction
Talbot patented his calotype process in February 1841. Unlike daguerreotypes, calotypes created a negative that could be duplicated by placing it over fresh light-sensitive paper, enabling mass production.
## Calotypes could capture movement
Calotypes required only seconds of exposure, making it possible to photograph subjects that couldn't sit still for the 3 to 15 minutes a daguerreotype demanded. This opened portraiture to living, moving subjects.
## Three steps that shaped film forever
Talbot's calotype introduced develop, fix, and print. These three steps became the foundation of analog film photography for over a century, even as the calotype itself was replaced by newer processes.
## Key takeaway

Talbot's discovery that invisible images on light-sensitive paper could be revealed with a chemical developer transformed photography from a hours-long process into a seconds-long one, introducing the develop-fix-print workflow still used in film photography today.
