Take a look at this beautiful Lexus how do they make it look so perfect? Not even the best camera could capture it exactly like that without any post editing methinks. Is this all air brushing?
this is a 3d image my friend. You can use 3dsmax, Maya or any 3d software to create a render like it. Then take your render image in Photoshop and adjust tones. Voila!! image is ready.
