Step 3
In the next step, we’ll simplify the image into two values – black and white. Before we do this however, it helps to adjust the overall contrast and brightness of the image. This will help Photoshop distribute the values in a more satisfactory way. Select Image > Adjustments > Brightness/Contrast and enter 80 for Brightness and 100 for Contrast. These values will change depending on the original photo. For this image, these values result in the desired balance of whites and blacks, so that the image isn’t too heavily biased one way or the other.

Step 4
We now want to reduce the image to two shades, black and white. Select Image > Adjustments > Posterize and enter a value of 2. For some illustrations, I’ll use a higher number to create more shades, but for this one I want to keep the image very simple.

Step 5
Go to Select > All, and Copy. Now, open the ‘Illustration Base.psd’ file. Paste the scooter into the file, which will add a new layer. Name the new layer Scooter. Now, using the Move, Scale, and Rotate tools, position the bike to match the placement seen in the example.
