Beside the 100'000 shots, the Taj is one of the most exiting buildings to experience; personally - as a architecture photographer - I find it more exiting than Peter's dome in Rome; I have seen both:
at first glance, the Taj looks like a symmetrical monument, but after a few days of visits, you realize its out of symmetrics, you understand better the fake and real (lower) tomb and the 2nd Taj, the
black one
Yes, it's not easy to take a genuine shot of the Taj.
