OMG!! how did you do that? How did you put those wheels on that car??? How did you drop that car? How did you change the color of that car?!?!
I decided to make a guide on how to do these basic things in Photoshop 5. Hopefully we can reference people to this when they ask these very common questions. I hope this comes out as good as i want it to.
Some basic Preferences you should have set in Photoshop:
Under "Display and Cursors" you should have "Painting Cursors" set to "Brush Size" and "Other Cursors" set to "Precise"
First One:
How do you put "X" wheels on my car??
First: Find a decent shot of your car and a decent shot of the rims you want to put on your car taken at basically the same angle.
Here are the two cars we will be using. Notice that the two photos are of a similar angle. This helps alot to make the swap look real.
Car 1
Car 2
There are many ways to select something in photoshop. For this Job the best tool for the job is the Elliptical Marquee tool (hotkey "M", if that doesn't change it to the circle tool, press and hold down over the tool until the tools pop out and then select the Circular tool)
OK, lets select the Turbo Porsche wheels from the red car.
Position your cursor over about the center of the wheel and hold down the Alt key while you select. This will make the selection originate from the center of the wheel instead of from the corner which is the default option for selecting. This makes it easier to select the wheel.
Now, hit Ctrl + C to copy the wheel to your clipboard. Now, switch your focus to the destination car, or the car who's wheels you wish to change. With the other car up, press Ctrl + V to paste the wheel into a new layer in that image. If you dont have the Layers window up, do so by going under the "Windows" menu and select "Show Layers". You will now see two layers, "Background" which is the car itself and "Layer 1" which is the wheel. If your two files where of generally the same size the wheel will be in correct proportion to the other car. If the two files had different resolutions or image sizes, the wheel will look either too big or too small. This wheel's size can be scaled under "Edit" -> "Transform" -> "Scale" or by using the Hotkey "Ctrl + T".
You should now have something that looks close to this:
Now, move the wheel into position over the old wheel using the "Move Tool" or Hotkey "V". If you selected some of the tire when you selected the rim, you can trim it off by make the Background Layer not visible by clicking on the "Eye" to hide it. you can then use the "Eraser" or Hotkey "E" to trim off the surrounding tire around the rim. Use the "Paintbrush" Option of the Eraser Tool and use a medium sized Brush, 20 pixles or so. Zoom in on your work to make it easy on your eyes and also hit "Tab" to temporarily hide the toolbox and any other non-document windows that are on the screen. Press "Tab" again to get them back.
With the tire trimmed around the rim and it positioned in the right place your window should look close to this:
Now that the rear tire looks pretty good we can concentrate on the front tire. Notice that for the front tire we will have to scale the rim down and transform it a bit.
Switch back to the "Move" tool (Hotkey "V") and with Layer 1 active, click on the wheel and hold the "Alt" key. Drag a copy of the rim off to the side and release the mouse button. This will make a new layer and a copy of the rear wheel. You will notice in your Layer manager that there is a new Layer named "Layer 1 copy"
Your Document should look like this:
Now, move the wheel into roughly the correct position over the front wheel. Press "Ctrl + T" to enter Transform mode. Use "Alt" to transform based on the center of the wheel. You will need to scale the wheel down, and rotate it a bit to the right to achieve the proper perspective for the wheel. To accept the transformation you have done to the wheel, simply double-click on the area inside the transformation box. Placing the cursor outside the transformation box enables you to rotate the rim. You will notice a curved, double-arrow-ended, cursor when you are in rotate mode. Always remember you can use "Ctrl + Z" to undo a operation you do not wish to accept. You can also use the "History" feature that Photoshop 5 offers to go back several steps.
Your document should look like this now:
You can now flatten all your layers if you like what you have and Save it as a new file. To Flatten Layers click the small arrow to bring down the menu, and select "Flatten all Layers"
This is basically how you change rims on a car using Photoshop. You may come across some variables that are not covered in this explanation. You will need a basic knowledge of computers and a slight knowledge of Photoshop to do this.
