A guy named Niepce made the first permanent
photograph in 1826. The exposure time was 8 hours.
7
Up to then, no one was able to make photographic
images permanent, though they could create them.
Niepce was a sort of hobby chemist who came up
with a way to fix the image he had created by
exposing a silver plate coated with a light
sensitive substance to light.
8
A guy named Daguerre, after Niepces death,
improved the process.

Boulevard du Temple -- 1838
The exposure time for this photo was 10 minutes
so traffic is invisible except for a man in the
lower left corner who stood still long enough to
show up.
This process is known as the Daguerreotype.

Daguerreotypes were the standard for many years.
This is Robert Cornelius in the first photograph
taken in the United states.

Color was harder. The first color photo didnt
appear until 1861.
12
Many famous photos were made with glass plates
coated with chemicals.
