Sketching with Paint
Sketching with paint is a wonderful skill to learn for starting a painting or as an actual technique for painting an entire picture. Sketching with paint is a form of painting loosely, just as sketching with pencils and charcoal is a loose form of drawing, only you’re sketching with a brush.
The beauty of sketching with paint is that it is a quick way to lay in a painting without being concerned about any details. For example, if you are painting a figure from a model or reference photo, you would sketch the motion (gesture) of the body and not attempt to do any details such as fingers and toes, or faces. Instead you would just be hinting at them. When sketching with a brush, you are recording visual information swiftly. The sketching with a brush may be done with a variety of stiff brushes (not watercolor brushes).
You can use one color of paint, such as burnt sienna, that has been thinned down to begin a painting and get your basic shapes down first, and then come in sketching with thicker paint to start laying in thicker colors. You can also establish where the light is coming from, sketching in your light and shadow areas with your brush. You can also do small sketches with paint before beginning a larger painting, such as the great sketch above in oils by artist Greg Dechow for a commission he worked on. Also, here is an “urban sketch” with paint by Brenda Malley.
