No way is this sweet Shelby Cobra performing a wheelstand on those street tires. Note the light showing through the tread of the rear tires, for there would be none if the car were actually digging into the road, not to mention some blur on the wheels of a moving tire. But the real tell is the front right tire, where the GA was rather sloppy with the edgework, as well as the clone stamp tool used to replace the actual tire with road imagery copied and pasted from, oh, just a few millimeters to the left, as evidenced by the repeating pattern of gravel and failure to color correct.

PS color isolation
In this Photoshop tutorial, you will learn how isolate parts of a picture that you want to be color, while other parts of the picture are black and white. This video will step you through taking a color image, turning it to black and white using the desaturate feature, then the procvess of painting some color back into the image by using the History Brush tool. This allows you to easily paint the original colors back into the picture, but only in areas that you desire.
