Generative Photography

Generative Photography [Processing]

In the last few weeks Ishac Bertran has been making experiments in the area of “Generative Photography”. He describes the process where the digital drawings are sequentially projected on to a screen in a dark room and photographed using long exposure times. As in generative art, this photography technique uses an algorithm that is polluted with a certain randomness. The randomness comes from rendering imperfections and the asynchrony between the frame rate of the video signal and the refresh rate of the projector.

Glitches are unique, almost impossible to reproduce, and usually imperceptible to the naked eye. This technique gives shape to these digital glitches and captures their unpredictable beauty…The experiments pursue an artistic exploration to achieve a certain aesthetic outcome more than a research on computer engineering…

Most recent experiments analyze the glitches caused by the rendering and the asynchrony between the frame rate of the video signal and the refresh rate of the projector. Running a Processing sketch and then photographed, he uses various photographic techniques including exposure, speed, framerates to seek out the glitches sometimes caused by the computer monitor or graphics card and sometimes what is caught in between the digital and analogue mediums.

Ishac has also set up a dedicated website where experiments can be seen generativephotography.com or track the progress on blog.ishback.com
