This yearly event is called “Die Lange Nacht der Museen”, which can be freely translated into “Museums all night long”. Here you can visit 42 museums in Hamburg for a one-time fee of 12 euros (approx. 16 US dollars), including the buses that take you from one museum to another.  It’s a great bargain, considering the regular entrance fee for a museum alone is around 7 euros in average.

There are hundreds of thousands of websites out there from which you can learn a thing or two about photography. To me, this guy has the best tutorials ever, both for beginners/amateurs and professionals.
He explains everything, from the types of cameras you should buy to how to sell your photos. If I’m ever successful in this area, I owe him so much.
