Here is a step by step method for how I did my "CARS" chops. Got some tips online, and I though I'd share it with you guys. Maybe we can all have our very own Cars Gallery! hahaha
Step 1: Get a photo of your car, for this one, I just used my Nokia N97, I think the photo is good enough. I wish someone could've taken a pic of myself with the car though.
Step 2: Go to the cars site at
www.pixar.com or visit
http://www.filmtotaal.nl/wallpaper.php?film=11702 and find a car mouth and eyes that suit your picture, It dosent mater if the car is facing left or right, or the perspective angle, all this can be edited later. I decided on using Lightning McQueen for my car. Open this wallpaper at the highest resolution.
Step 3: with your CARS wallpaper and using the freehand lasso (newbies) or pen tool select a large area around the mouth. Make sure you include all the mouth corner lines. this selection dosent have to be perfect.
Step 4: Drag the mouth to your car photograph and set the opacity to around 75%
Step 5: If your chosen character's mouth is backwards go to the edit menu>transform>flip horizontal. Now comes the hard part: using the transform functions (rotate, scale, and a lot of perspective) drag the mouth around so it covers the area of your front bumper. I find it very easy to use the foglight holes as a refferance, putting the edes of the mouth just a little bit over the inside crease (blue) just make sure you pay attention to the bottom and sides of the mouth (red) and that the perspective of the mouth fits the perspective of the car
step 6: go back to your wallpaper and using the polygonal laso select a general area around the eyes/windshield. again this selection dosent have to be perfect just make sure you're outside the windshield.
Step 8: Drag the eyes over to your photo and set the opacity to around 75%. Ok, as with the mouth you have to use the transform tools (rotate, scale, A lot of Perspective) to fit the windshield around your own windshield (pat attention to the perspectives! (blue lines) this will make the differance between something that looks realistic and something that looks weird). Pay attention to the eyebrows, make sure the color goes all the way to the top corners (red) make sure your eyes.
Step 9: hide the visibility of the eyes layer (the little eyeball in the Layers Pallet) and very carefully using the magnetic lasso or Pen tool select around the edge of your windshield. you want to select under your windshield wipers. Then go up to the menu Select>Feather and set that to 2 or 3 pixles (a little more if your using a big file)
Step 10: Select the inverse (ctrl+shift+I) and without deselecting anything, click on your CARS eyes, make it visible again (the little eyeball) and press delete. this should trim around the edge and make the eyeballs fit your windshield, Now you can play with the opacity, to preserve the reflections in the windshield I think about 85% is good.
Step 11: Going back to the mouth, make sure you have the brush pallet open (Press F5) and select the ereaser tool. pick a fuzzy brush (see below) thats about 10% the size of the mouth, start ereasing around your mouth to remove all hard edges, make sure you dont erease any of the actual mouth.
Step 12: Set the opacity of the mouth back up to 100% and using progresively smaller fuzzy brushes erease the rest of the color that covers the fog lights (if your car has any), grill, under the bumper, headlights. basicly everywhere that isnt solid paint (Red)
