Old and New
The photo gram required us to take pictures of a variety of patterns (from pattern and structure) Using the enlarger we placed different objects to create interesting effects on the photographic paper and did a test strip to work out the optimum exposure time. The optimum exposure time for this photo gram was 6 seconds. Then to create a warped effect, instead of covering the whole paper in development we splashed it on.

History of photography
Before the 16th century the first camera that was able to project an image was the camera obscura which formed an upside down image on a wall. Louis Daguerre was able to reduce exposure time to less than 30 minutes and keep the image from disappearing afterwards.This became known as the Daguero type. By 1834 Henry Fox Talbot produced permanent negative images and positive images by contact printing onto another sheet of paper. This was known as the calotype. Then many other processes followed such as the wet plate and film rolls. Then coloured photos were invented in the early 1940's.
