Paris photography

I was in Paris at the weekend, and a bit depressed that I was so uninspired in terms of photography. A city of lovers and culture, but pictures...not for me. I don't know, may be it was the time of year, or that I went to the wrong places, or that Paris just kept her soul well hidden, but I didn't come up with much. I think I prefer to set up photos rather than take pictures of things that already exist, or have a kind of project in my head. I like to fall in love with the idea of a potential picture, love the subject, not sure that I liked Paris enough last weekend to do a portrait of her.
