I have been doing a number of workshops at both the Byron School of Art and the Lismore Art Space. The focus of these workshops have been to show students how to create photographic images using alternative techniques and processes.
Late last year I started workshops teaching the art of Solargraphy, creating images with long exposure times using an empty can and photographic paper. The image below is a 5 hour exposure.
The principle of Solargraphy is not unlike pinhole photography, except black and white photographic paper is used resulting in a negative image exposed on the paper. This exposed piece of paper needs to be digitized using a scanner or iphone in order to invert it into a positive image using Photoshop or an other photo editing program.
Below a shot of the Solargraphy ‘camera’ and subject and the result after a 4 hour exposure.
Here some examples of longer exposures.
