When filmmakers in India switched to the digital medium sometime between 2008 and '13, the swiftness of the process was a welcome change. But what tipped the scales in favour of the new technology was the cost factor — the need to replenish physical film every time it got wasted because of a bad shot or other ambient conditions was no longer a worry.

But you would also perhaps agree that those were the days when a badly captured image was sacrilegious. So, each one of the 36 photos was worth its place in the family album.
