Bit bored today, so I grabbed a photo and started editing, here is an example of how much you can touch up an image:
Before: (Original image posted by Peytonracer Here)
After:
Chopped the roof (looking for a stylized look), added some more to the left side of the image (attempting to balance the image a bit), set the levels (helped bring out the car a bit, and kill some of the blown out highlights), Dodged and burned (bring the sides of the car to a new level), dropped in a white gradient (to drop the hopper out of interest).
Thanks
Ryo
