I'm not sure whether I got your request correctly but if you need tips in the artsy direction,..
first of all youre gonna love Berlin. ^^
me I have a preferance for street art and that city just is full of it.
you need to experience the part of the city called Prenzlauer Berg. The whole atmosphere is just amazing and especially if you wanna take photos.. got there. I loved it
also, next to the Hackesche Höfe (who, themselves, are a popular sight in means of art and architecture, youll find them in any guide), actually right ebside them is the Haus Schwarzenberg which is house full of art projects. even the entrance looks great, theres a gallery in there and s hop with not-yet-so-known berlin artists, selling cartoons, buttons, books, just anything. its really enchanting
oh and go up the TV tower by night. it looks so nice
hope I helped you and didnt completely miss your point^^
