Wow, here, taking a camera into any store or outlet is strictly forbidden. I tried once, and seriously within like 2 min, security tried to take my camera and throw me out.
I like them, especially the long aisle shots. Although I would also recommend B&W for the cocacola one. Just a thought.
That's a pretty friendly market to let you take pictures.
I wanted to take photos at a supermarket once. They gave me a number to contact the marketing department and wanted me to sign a bunch of papers saying that I wouldn't use any of their images for my own personal benefit (meaning, no selling and no using them in my portfolio). So said no thanks to the whole ordeal.
THe times I have been dragged shopping with the wife under total hatred of the place ... now I think I might take the camera and see what I can do .... but doubt mine will be this good.
