re: Good cities to photograph in Louisiana other than New Orleans?

I would recommend both Natchitoches and Natchez...old towns with a lot of character and some pretty cool areas...

Alexandria has some interesting stuff with the brick streets and whatnot....be careful where you go, though as some of it is in parts of town that are pretty bad...

you may also want to check out the Mississippi delta towns like greenwood, Clarksdale, Cleveland, etc...

if it is nature that you are looking for, take a drive up the natchez trace and stop at every historical marker....there is some very cool stuff including a "ghost town"....
