the almost perfect postcard picture! It would be perfect if the small building left below would be totally in or out the picture ;-P

Wow! I've never seen such blue sky in Shanghai!
Indeed, it is a perfect post card picture. Can you send it to me? :o)

Small building got chopped while adjusting perspective in pp, need wider lens :-)

There's blue sky for a few weeks/months a year. The advantage of staying one year plus and having a few months holiday so you can go outside during the daytime, sometimes you get to see something special :-)
