One of the best places to use a long exposure. So much movement but there are always people standing still. Great shot with the trails of moving people
1. why is it not centered?!
2. this is where the light meter f'd you in the a. let the camera meter for you, and you get blown out at the windows and underexposed everywhere else. but this is where you can duplicate a layer, fix the surroundings until it's properly exposed, and then erase the window part.
a good idea behind a good image. but you can do better.
