Prague fall is often a good time for walking around the city in rain and cold. Many people seek warm cafes and tea houses and watch the street from inside. But to get interesting photos best is to go out just after the rain or at dawn. The light and reflections can be quite beautiful. They will transform the streets into brand new visuals. And modern buildings such the Dancing House are often the most beautiful at night with all the colorful lights on and even the traffic lights and lights from the cars that surround it.
I love taking pictures of the city after the rain and at night. Even if it is just with a mobile phone. The picture can be blurry but it has sometimes more atmosphere and more spontaneity than a perfectly sharp photo from an SLR on a tripod. 🙂
