Photographic history was made in the early part of last century, when
French painter Louis Jacques Mande Daguerre made the first successful
photos which included the following (6):
Historical Photographic Innovations
This process did have its drawbacks which included the following (6) :
- when copper plates were exposed to iodine, the fumes formed
light sensitive silver iodide.
- depending on available light, this exposed to light for 10 to 20 minutes
- the plate was then developed over mercury to about 165 degrees
Farenheit. As a result, the mercury amalgamated with the silver.
- the image was fixed in a warm solution of salt.
- the plate was rinse in hot distilled water.
Other sources say that French inventor Joseph Niepce made the first
photographic image using a bitumen-coated pewter plate exposed in a
camera obscura, forerunner of the camera. (6)
Many people would invent diverse tools and develop processes that would
allow photography to be more than just an inexpensive pasttime. The
following charts represents some to these inventions that helped shape
the trade and art of photography into what it is today.
- the pictures could not be reproduced.
- the surfaces were delicate.
- the image was reversed.
- the chemicals, bromine and chlorine, were toxic.
