As Candybabe says, depends who you are taking photo`s of, children are usually fine (couple of rupees or some sweets), if you come across any of the hippy travellers be very careful as they don`t really like cameras pointed at them and i have seen cameras snatched and film removed, this also goes for any holy men. Asking first if in doubt is always the politest and best way to deal with this situation...... Happy snapping ;-)
