Last month Porsche flew over six cars from their museum in Germany for the 60th Anniversary which was being celebrated in Shanghai. They originally wanted me to shoot them on locations around the city but due to a limited amount of time I had to instead photograph them in a container yard and photograph the backgrounds later. It seemed like a good idea at the time because instead of traveling around the congested city with a convoy of trucks and the hassle of loading and unloading priceless cars I could wander the streets shooting freely. But then it came to drop in the cars and of course while I matched the camera angle, camera height and lens used it's been a bit tough getting the shadow's and lighting on the cars just right.
Below is a shot of the GT1 which was the winner of the 1998 Le Mans 24hr. While I think that the retouching is close I'd appreciate some feedback about how to make it better.
