Photography! Who could have thought that we would at this moment be able to take pictures through a digital camera and transfer to a computer and alter the colors or any of the properties of a picture or a photograph? Digital cameras are sharper and provide high quality photos that could be utilized over multiple mediums.
Sir John Herschel is the man who invented the term ‘Photography’ in 1839.
This was also the year when the process of Photography was unveiled to the public.
How did photography really evolve? Well! It is the bi-product of laws of physics and compounds of chemistry. The evolution of photography is a totally scientific process starting up with the use of optics in the 1830’s.
The dark room or Camera Obscura endured some four hundred years back, though cameras had been being used ever since the 11th century and yet photography did not come into public use prior to the 1830’s.
There were different observations created by several individuals that ultimately led to putting together of all the missing pieces and this also introduced the advent of photography. Some of those essential observations are:
* In the 15th century, Robert Boyle discovered that silver chloride became dark if open to air and not light.
* In the early 1800’s Angelo Sala noticed that when silver nitrate powder is kept in the sun for long, it turns black.
* Around 1727, Johann Heinrich Schulze made a discovery regarding colors. There were some liquids that changed their colors when they had been exposed to light.
* Thomas Wedgwood conducted a few experiments in the early 19th century. He had captured images but could make the images permanent.
* The first ever successful production of a photograph came about in June-July of 1827 by Joseph Nicphore Nipce. The material utilized for this turned out to be solid when exposed to light for almost 8 hrs. Nipce went into a partnership with Louis Daguerre on 4th Jan, 1829 to work further on this.
Four years after in 1833, Nipce passed away and Daguerre continued alone to discover how to develop photographic plates. Invention of the photographic plates supposed that the exposure time was decreased significantly, from 8 hrs to 30 minutes. He also created one more important observation and the conclusion drawn was that immersing an image in salt would make it permanent.
