The cemetery in the Josefov quarter of Prague is deservedly famous, but that fame also means hordes of visitors and restrictions on photography.  On the morning that I visited, the cemetery was overrun with tour groups; however, when I returned in the afternoon, the visitors were mostly small family groups, couples, and individuals which made for a calmer and less hectic atmosphere.  The stones were interesting, but also difficult to photograph given their close proximity to each other.  I did find a small seating area at the exit to the cemetery to be a nice place for some quiet contemplation.
