I only have a limited version - Photoshop elements 3.0...
For the chrome, I selected with the lassoo tool all the panels I wanted to chrome, then copied them to a new layer. Then it was a matter of fiddling with the levels and colour saturation. Its not an exact science for the chrome effect, you just have to keep adjusting until it looks right. As I de-saturated the colour it starts to appear chrome.I'm still figuring things out. How did you make the paint chrome, or any other color? Help is appreciated.
you still have a reflection on the side on car, the sky layer isnt trimmed enough at the bottom and lighting effect isnt even through the picture. overall not to bad of a job.
