> I left home with 500 rolls of film in my backpack. It was close to $5 a photo in today's money just to develop and print the photos. So I had to really think about it each time I pressed that shutter.
At 24 frames per roll, the cost to develop and print his entire backpack would be 24 x $5 x 500 = $60,000. That is indeed a big investment he made to document his travels.
