Yes David, you are right.
These are real photos. The head of Ford France confirmed it to me, yesterday.
Living in Paris myself, I can say that it is a feat to empty these places and take such pictures, even at night.
The talent of the photographer is remarkable, and his work for the light on the car is extremely successful.
I am really surprised they went that road. Since you always have to factor in weather conditions it is a huge risk to go that way. The problem with todays advertising photos is that the final result has little to do with reality, every single pixel of it is being reworked afterwards to give a special look. Take a look at the paint, in real photo it is almost like a mirror finish and you see lot's of paint imperfections (and dirt of course). In ad photos there is almost no reflection or just a lighted reflection line to let the car look more dynamic (no reflection of illuminated white scare coeur ?). Or it is kind of blurred like you see in the front of the car. The backgrounds look like being made with HDR technology and artificially tonemapped and the colors do not look real (but dramatic). So there is a whole lot of work being put into to get the final result. Don't get me wrong the team from the photographer did a very good job. But the lines between an authentic photo and what we conceive as a photo have been blurred a lot. In automotive industry more than 95% of every image you see is computer generated. For example almost all realistic looking images of the NGT at the Ford Development Center were being produced with such a software, simply because at that time only CAD data was available and not a single part of the car. In the case of the Ford (like the majority of all automotive companies), they are using the same software like being shown in this video.
