Trained as aphysicist, Rahul got interested in light, optics and per- ception. For a while he married his interest in photography with his profession and worked on visualizing turbulent fluid flows and then damage in high-power laser optics. He has won international awards for his flow visualization work and more recently won local, national and international awards for his photography. His work concentrates on the interaction between light and his subjects, preferring to shoot in natural light. Rahul prefers not to edit photographs, spending the time up front to get the exposure right to achieve the desired effect right in the camera. An avid traveller, he particularly enjoys photographing landscapes, animals and birds. Check his website http://500px.com/rrprasad.
