What about the Wiltern? That s pretty cool. Or just about anything on Wilshire. Great art deco archiecture between downtown and Beverly Hills.Larchmont area has cool houses.Make sure you have a permit. A permit is required for commercial still photography. Avoid heavy fines and penalties. http://www.filmla.com/getting_started.ph��(I m not associated with these folks, but did see a photo shoot get shut down right in the middle. The photog started to put up a stink, and the cops started treating him like he was bin Laden. Moral of the story: Get a permit.)
hmmm, I have taken pictures all over greater LA with tripods and a commercial looking set up and never even knew a permit was required for professionals stills, and never had ANYONE SAY ANYTHING TO ME ABOUT IT...I am going to guess you are shooting for some kind of urban pioneer/Ed Hardy type fashion and not some high end Rodeo Dr. type fashions....I would go to the northwest fringes of downtown (near the old trolley tunnel). I think you could get some good pics there. (Hint--take some BIG guys with you---LOL)....Good shooting, hope you get good light....
You can try the Angelino Heights area between Sunset and Temple Streets near Douglas, west of Downtown; and yes just like the person mentioned above watch out for the Photo Police.
