Big buildings, whether day or night, are so fascinating that people can't help stopping for them. They can only take panoramic views of the street when they are self-portraits. OK. The bad thing about traveling alone is that nobody can take beautiful pictures for you when you don't want to find a passer-by. I was deeply impressed by the atmosphere of London's ancient attractions and the surrounding human scenery. Some people have said that if you've been to London, you'll never be able to go to another city. On the other side of the river, you can photograph the whole building complex of the Parliament Building, which is very spectacular in the afterglow of the sunset.
