Man fascinated by time travels the country to recreate scenes from yesteryear

Most tourists travel through space. Dheera Venkatraman also travels through time.

Enamored by photographs taken in China a century ago, Venkatraman has traveled across the country by train, taking photos in the same places as the historic images, comparing the past with the present in an ongoing project, Time Traveling in China.
