Plein Air Painting Demo in Acrylics by Donald Neff

Artist Statement


“I paint the places I love to be. I paint the freshness of eternal nature, icy lucid streams, thunderous waterfalls, and soaring granite crests over silent lakes. I paint the descriptions of John Muir, the echoes of Ansel Adams, the American West of Albert Bierstadt and Thomas Moran. I paint luminosity filtering through the landscape, reaching to the foundation of a stream, bouncing off rocks, and illuminating the shadows.

Using oil and acrylic, painting realistically is merely my means to an end. I want the viewer to connect with the places I love to be. I hope the observer will want to walk right into my painting and maybe even drop a line in the water to catch a trout.

My published works include both “plein air” and studio paintings, which helps me translate the dynamic experience of the moment and communicate in a more personal way of what I am trying to say..”

Acrylic Landscape Painting Tutorial By Donald Neff

acrylic painting demo sceneIt was a winter day and not much light. I did however locate a nice pool at the west end of Yosemite Valley. This is a snapshot of the scene.

In the low 30’s, it was barely warm enough to do an acrylic painting. Since acrylics are water soluble, it is difficult to paint in below freezing weather!

acrylic painting lesson 1After locating the scene I wish to paint, I pencil in a quick sketch of the scene. I want to capture the colors and reflections of the river, so set the horizon line high with the large rock towards the top of the painting.
acrylic painting tutorial 2This is a shot of my palette. When I paint outdoors in acrylic, I use a paper palette. I don’t mess with any type of ‘stay-wet’ palettes or boxes as I usually paint fast and use a spray bottle to keep the acrylics from drying.

My palette here consists of Thalo Blue, Ultramarine Blue, Quinacridone Red, Cadmium Red Medium, Raw Sienna, Burnt Sienna, Dialiryde Yellow, and Cadmium Yellow Medium. I use other colors, but for today, that is my choice.

Before I get too much into the painting, I usually mix a combination of Ultramarine Blue and Quinacridone Red to form a purple. I also sometimes mix Thalo Blue and Cadmium Red Medium to get a rich gray.

acrylic painting techniques 3I next block in quickly the general colors. I do this primarily to get rid of the white so as to judge values better as I go along. Many times I prepare my canvas with a coating of Yellow Ochre or Burnt Sienna to tone the white. However, today, I am starting with just a white canvas.

For the background, I am using the mixed purple. The other areas are from the mixed gray. The water is Cad Yellow Med and Thalo Blue.

I usually try to let this stage dry before going on. Outdoors with acrylics, this generally takes only a few minutes.

Here I have blocked in more of the distant mountain and the sky. I am using the same basic colors as the previous block-in.

I work the entire painting again, giving everything another coat of color.

I generally do at least three complete layers over every part of the painting before it is complete. Acrylics tend to be thinner than oil, and this multiple coating technique builds different colors over one another giving more depth and feeling to the painting.

I start adding some Sienna to the water in the middle ground which are the rocks in the bottom of the river.

For the large rock I switch to a palette knife. The paint here is laid on fairly thick to form the consistency and sculpture of the rock. I use the premixed Gray and add Burnt Sienna, premixed Purple, a little Sienna and others to give the rock more texture and color.

For the darks in the stream bottom, I add Burnt Sienna, and sometimes the purple which I mix from Ultramarine Blue and Quinacridone Red.
acrylic painting tips 8I continue working on the foreground pool and begin to sculpt in the smaller rocks with thick paint and a palette knife. I used the premixed gray along with Sienna for these rocks.

I also begin to develop the reflections and patterns in the bottom of the pool.

acrylic painting beginners 9I continue to work on the pool, working the deep greens into the reflected light.

I also start adding in the reflected light in the pool. I do this by dabbing a little light gray at the top of the reflection and then pull it down with my finger.

acrylic painting technique 10I keep adding more reflection on the surface of the water. Since the under painting is dry, it is easy to drag down a wash of grayish white to indicate the reflections of the rocks. I also add some white sparkles around to give the effect of the glinting water.

One of the advantages of acrylics over oils is glazing can be quickly done in the field. With oils, you would have to wait days for the painting to dry in order to accomplish the same effect.

I spent just under two hours on the painting, and this is the way it looked as I was finishing it on the scene.

acrylic painting lesson 11Here is a photo of the scene when close to finished with the painting. I forgot to mention, it rained, sleeted and hailed while doing this study. You can read more about that day and painting on my weblog.
acrylic painting demonstration finalHere is the final painting. After I got home, I realized the light reflection in the water detracted from the overall scene, so painted some of it out and grayed out the rest.
