Lifting Out Color
Another way to preserve the white of the paper is to lay down color and then “lift out” some of the wet paint by blotting it with a tissue, a cotton swab, or a paintbrush. If you’re lifting out paint to create highlights, keep in mind that you can’t control the shape of the lifted area as precisely as you can by painting around the areas that you wish to remain white, so this method is more suitable for soft, diffused highlights than for sharp, defined ones. You also can lift out dry paint; simply moisten the area you want to lift with clear water, and then blot the area with a dry tissue or paintbrush.
CREATING CLOUDSThe lifting out technique is perfect for creating soft, billowing clouds. First apply a blue wash for the sky. Then, while the paint is still wet, blot an area of paint with a tissue until you’ve created the desired shape. (It helps to just slightly dampen the tissue by touching it on your tongue.)
