Malvern Photography – The Evolution Of Photography

Photography! Who could have thought that we would at this moment be able to take pictures by means of a digital camera and transfer to a computer and change the colors or any of the attributes of a picture or a photograph? Digital cameras are sharper and provide high quality photos that can 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 revealed to the public.

How did photography truly develop? Well! It’s the bi-product of laws of physics and compounds of chemistry. The evolution of photography is a completely scientific procedure starting up with the use of optics in the 1830′s.

The dark room or Camera Obscura existed some four hundred years back, though cameras had been being used since the 11th century and yet photography did not come into public use prior to the 1830′s.

There had been various observations made by several individuals that finally brought to putting together of all the missing pieces and this also announced the advent of photography. Some of those essential findings are:

* In the 15th century, Robert Boyle found out that silver chloride turned dark if exposed 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 with regards to colors. There had been some liquids that changed their colors when they had been exposed to light.

* Thomas Wedgwood performed some experiments in the early 19th century. He had captured images but could make the images permanent.

* The first ever successful production of a photograph emerged in June-July of 1827 by Joseph Nicphore Nipce. The material used for this became hard when uncovered to light for almost 8 hrs. Nipce went into a partnership with Louis Daguerre on 4th Jan, 1829 to work more on this.

Four years later in 1833, Nipce passed away and Daguerre continued alone to discover how to develop photographic plates. Invention of the photographic plates meant that the exposure time was decreased significantly, from 8 hrs to 30 minutes. He also created one more important remark and the conclusion drawn was that immersing an image in salt would make it permanent.
