This needs to be approached at a far lower angle. Looking down on the car with a super wide angle lens just doesn't work. Plus, the camera strap... I mean, come on. At least crop that out.
Jaime, there are a few problems with the HDR processing and all you can see is a bit of camera strap. You have a sharp eye. A dull brain but a sharp eye.
Thanks for the reply. I only have one exposure for this picture. I loaded into photomatix pro " batch single photo" and have it do the rest of the work. After that, I polish it using Adobe Photoshop Lightroom 4. I'm using Sony NEX 5 camera.Your second attempt is better. However I still think the shot you are using will not justify the car. But, I also like the way the fisheye looks just put it work in a different perspective.
You asked how to make your car look white, funny I thought it was silver. Do you have enough exposures? What software are you using?
Once we know this we can lend you a hand, but, before you post again use another perspective.
