Paint on the canvas or layer. First try painting a few strokes and turn off the Impasto Effect and notice the change in the brush stroke. If I wanted to continue to paint with a flat stroke instead of the Impasto effect then I would change "Draw To" on the Impasto palette to simply Color instead of Color and Depth. Try this and experiment with some brush strokes. It is important to note that you can add additional layers and paint with Impasto on one layer or selection and then choose "Paint With Color" on any additional layer. It really is up to your imagination. Just remember that you can paint with or without the effect on any layer or selection.
