Rob Turney, Refractograph, 2015, Refraction and reflection of light through glass manually coloured and captured over a long exposure photograph, 170 cm x 80 cm (approx.)
I capture the patterns of light produced by the refraction and reflection of light as it passes through everyday household objects – in this case a beer glass.
The light patterns, or optical caustics, are projected directly onto a DSLR camera sensor without a lens attached. My technique involves using coloured gels to manually colour and control the image over a long photographic exposure, usually from between 5 to 15 seconds. I am continually evolving the method though experimentation and innovation.
Different household objects produce completely different patterns and changing the angle of the object by a few degrees will change the composition dramatically. Each capture is unique and demonstrates the abstract and complex nature of light.
Through the use of common household objects I attempt to connect the everyday with the phenomenon of light, demonstrating how light is an essential part of our lives.
