Changing Wheels in Photoshop
by addnon
Chopping rims in Photoshop is one of the easiest things to do once you learn how. It seems that a lot of people have their own way of doing this, so I figured I'd post mine.
STEP 1: As with all chops, you want to start out with a clear, high-resolution picture. For this tutorial, I chose the Z4 coupe concept (for obvious reasons :D ).

STEP 2: Next you open up the rims you want to put on. I chose CSLs, because I knew there are dozens of high-res pics of the M3 CSL with the angle I'm looking for. It is essential the picture of the rims you are putting on is the SAME res or bigger. Making big rims smaller is okay, but making smaller rims big will result in distortion.

STEP 3: To help you select the wheels effectively, we will use the guides and snapping. Make sure rulers are showing (checked) and make sure you select Snap to > Guides.

STEP 4: Click on the ruler on the top and drag a blue guideline out of it (click and drag). Position it a fraction above the top of the rim. Do the same thing vertically.

STEP 5: Now select the circular selection tool.

STEP 6: Click where the two lines meet and drag around the wheel.

STEP 7: Copy the wheel, and then switch back to other file.

STEP 8: Paste the wheel (should automatically put it into a new layer) and position it. Resize if necessary.

STEP 9: Now we are going to fix the colors on the wheel to make it match better. You can do this in a variety of ways: photo filter pass, brightness/contrast, levels, saturation, etc. I'm going to de-saturate it a little bit in this example. Because I’m going to "take away" the color and I want to retain the emblem color, I'm going to select around the emblem. To do this I first select the emblem, then I right click and pick "select inverse". This will now select everything around the emblem.

STEP 10: There is no set rule on how much to de-saturate. Just do what you think looks good.

STEP 11: I am also going to decrease the brightness a bit.

STEP 12: Duplicate the layer (CTRL + J) and position it over the rear wheel.

STEP 13: To make it look slightly more realistic, we want to rotate the wheel so it looks slightly different from the front. Press CTRL + T to go into transform mode. Move the cursor to the corner and you should see a little curvy arrow pop up. Turn the wheel to your liking.

STEP 14: Done! Now resize your work and add any finishing touches.
