A marvel in the history of photographic processes, Collodion photographic process or Collodion wet-plate process was presented in the year 1850. It was almost concurrently invented by Gustave Le Gray and Frederick Scott Archer during that year. The wet-plate collodion process is known to have entirely replaced the ‘daguerreotype process’, which was widely used during early 19th century.
Tintype photographic process is also known as Ferrotype and Melainotype process, which is very similar to the typical wet-plate photographic process. This process involves creation of positives directly on a metallic sheet (usually iron), which is later enameled, lacquered or painted black. The directly obtained positive image may be used as a support to the Collodian photographic emulsion.
Gum Bi-Chromate photographic printing process was widely used and popularized during the early nineteenth century. It was in the year 1839 that a Scottish inventor Mungo Ponton discovered that dichromates are a class of chemicals, which are quite sensitive to light. In the later years, William Henry Fox Talbot found out that certain organic colloids like ‘gum arabic’ and gelatin didn’t dissolve in water when exposed to light. Talbot and Ponton’s observation about dichromate and colloids was exploited in the later times, by Alphonso Poitevin and John Pouncy.
Photography has come a long way since the time it was invented. With newer technologies emerging, the way people take photographs has changed a lot. Digital cameras, the cameras of 21st century, are the best thing that has happened to photographers. So much is their popularity that professional and newbie - all kind of photographers have these cameras. What's more, with the rising use of internet, people can even buy their cameras from the comfort of their homes. So what are these digital cameras and how has it changed the way people capture their memories?
In the modern age of sophisticated photographic technologies, which can produce vibrant colors and majestic visual effects, a black & white silent movie titled 'The Artist', bagged five Oscars out of its ten nominations. This is an incredible feat for a film shot in a basic color format that was used in earlier days.
