I absolutely LOVED Copenhagen. I was only there for a day but I will be back in the city on Tuesday. It is extremely clean, (much cleaner than SF), there are few cars, tons of beautiful squares, extremely interesting people, etc. -basically it epitomizes the ideal European city.
Here are a few photos from Copenhagen ( I have much more I will upload later)

Nyhvan-very colorful place

(This photo actually was not taken in Copenhagen, but it was shot nearby. It is of Fredericksburg castle, which housed the Dutch royalty)




The last picture is not a HDR by the way, for those who may suspect it. It did go through some post-processing to reveal the detail in the tires etc. but not too much. The 2nd to last photo also went through some extra post-processing to create the dominant green tone.
Amsterdam
I loved Amsterdam as much as Copenhagen! Walking through the Red Light District and feeling uncomfortable looking at the prostitutes selling themselves in the window was a bit much, but it is still a very interesting city. Seeing tons of people do weed casually while eating outside was also quite interesting and different. I haven't uploaded/looked at a lot of my photos from Amsterdam yet, but here are 3 from the 20 or so I did look at.
Reguliersdwarsstraat
