This blog post will be more work from my Unit 5 Contextual Influences in Art and Design. Today we will be looking at as the title implies Historical Photographic Processes. We were all given different processes to look at and create a simple summary of the process. I was given the Camera Obscura and Daguerrotype to research.
Process: Camera obscura
Photographers/Artists associated with process: Abelardo Morrell
What is the Camera Obscura?
A camera obscura (this is Latin that translates to “dark chamber”) is an optical device that paved the way for photography and the camera. The device is made up of a box with a hole in one side. Light from outside of the box passes through the hole and projects onto a surface inside, where it is reproduced and rotated 180 degrees, but with color and perspective preserved. The image can then be projected onto paper, and can be traced to produce a highly accurate representation of the scene you are looking at. The largest camera obscura built in the world is on Constitution Hill in Aberystwyth, Wales.
Process: The Daguerrotype Printing Process
Photographers associated with process: André-Adolphe-Eugène Disdéri and Johann Baptist Isenring
What is the Daguerrotype Printing Process?
A Daguerreotypist is someone who prints under the Daguerreotype Process. Daguerreotype was introduced in 1839 as the first publicly announced photographic development process, and that had widespread use.
To make a daguerreotype, the daguerreotypist must polish a sheet of silver-plated copper to a mirror finish, treated with fumes. That makes the surface light sensitive when it is exposed in a camera. Depending on how long the exposure is judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting
There will be a few more posts on my Unit 5 Contextual Influences in Art and Design, the last post will be the essay as the concluding post. Sorry for the layout formatting issues, WordPress was having trouble with the image arrangement.
