Thank you 4xxxx.
Many of the shots were in very overcast and drizzling weather or from moving train/car or taken at night. So pushed up ISO to get faster shutter.
India is a country with huge difference in life styles of people. I find character (from photographic point of view) in the lot not so affluent, those who express themselves in their own way. For the patrons of Gucci, Tommy Hilfiger, C&K, Armani and other brands, there is not much difference from what I've seen in some other parts of the world - prototypes with different features may be.
Yes, the train was stopped
It is a strange mindset that exists in people of developing/third world countries that forces them to certain actions which they just fail to understand how dangerous the impact may be. I feel 'Third World' is a mentality which is next to impossible to change drastically and for this reason developing countries will continue to remain 'developing' without reaching the 'developed' phase.
