I sure loved out our visit to China, even Beijing was a lot better than I thought it would be, but man… I do not have fun processing the sky in my Beijing shots. Even at night it is kind of a dull grey and very noisy result. The sky in my posted image is still rather bland, but I had to use a lot of blur tool on the sky to clean it up. I would definitely look into getting a polarizing filter for any lenses you take with you to Beijing.
When we were in Beijing, we took a quick trip on the subway to see some of the more prominent Olympic venues. The buildings were definitely out of this world, especially at night, with all of the progressive designs that were implemented into these buildings and the amazing color they are lit at night, they were very photogenic. However, Every single building is blocked off with an unsightly fence. This is the best picture I could get of this building, and the closest as well. Maybe they open the gates up at certain days, but this is one of the few dissapointments I had on our trip. I really wanted to get some good up-close shots of some of these venues..
