I was in India in Feb (Mombaai and Pune) and film was freely available in the cities I was in (35mm and 120) although I did not buy any. Villages are a different matter.

The locals were very accomadating and hospitable and I dont think theft is a high risk. I certainly never felt threatened. I would say the camera opened doors there and most people were very willing to have there pictures taken. Some people actually asking. It seemed that cameras were a novelty, as was being an european, once out of the city. The only exception to this were the 'illegal' couples (arranged marriages are the norm) trying not to be photographed together in the local park on the Saturday morning. No hostility, just mild evasion.

Culturally there are endless differences which makes for lots of photo's.

Good luck and happy shooting
