Another significant part of his career has been the photographical documentation of the UNESCO World Heritage Site - Champaner-Pavagadh, near Baroda. Over the last three decades, Rahul has captured its many moods – at different times of the day and in different seasons of the year. The result of this diligent effort is an outstanding collection of more than 50,000 images of the site! Besides this, his portfolio includes 12 Indian and 6 international sites and he is now involved in documenting 32 existing UNESCO World Heritage Sites of India.
