The constant stream of young customers at Capital Camera, a small but incredibly busy store in Delhi’s Nehru Place, hasn’t thinned. Through the year, even on weekdays, they trooped in, eyed the dSLRs wistfully, asked questions about pixel and zoom and tested the compact cameras. Most left without buying anything. That changed in the second week of October. With Diwali round the corner, sales manager Advait Kumar had enough business to keep him occupied at the cash register through the day, rather than stand behind the counter passing out the same cameras to every potential shopper.
