PHOTshading

SET UP: Run Photoshop. Find a photo of a student (take in class with our camera) open (File: Open). Avoid black clothes for this exercise! Next, adjust the light (Image:Adjustments:Shadow & Highlight). Save your file as YLNIshadingex.

Step One: Add a layer. Using the pencil, make a line drawing of a garment (shirt, pants, etc.). Be sure your shapes are closed. In a separate layer, fill the garment you have drawn with a solid color. When complete, turn the line and color layers off.

Step Two. Reselect your photo layer. Go to Image: Adjustments: Posterize. Begin by experimenting with Levels: Try levels 3, 4 and 5 until you have a several clear color areas that describe the highlights and showdows in your figure. (Note: In order to achieve excellent shading, it may be necessary to use more than one posterization. To do this simply make more Layer copies of the original photo. Be sure to preserve the original photo.)
Step Three: Using the magic wand, select a shadow or highlight area. You may wish to gather up several areas of the same tone by holding the shift key.
Step Four: With the areas selected, go to LAYERS and turn on the corresponding colored layer. Create a New Layer.

Step Five: Go to the Toolbox and use the Eyedropper Tool to select the base color. Next, doubleclick the color chooser. Choose a shade of your base color that is lighter or darker than the original. Return to your New Layer and fill.

Step Six: Continue, until you have at least two values darker than the base color and one shade lighter. Use more if necessary for the look you require!
