I combined lesson 41 and 42 of Drawing and Painting the Landscape by Philip Tyler.

Lesson 41 is about Scumbling - the application of paint as a broken layer. Philp suggests scrubbing the paint on to the surface. This:

"causes the paint to go on really thinly, making for an optically porous surface (the ground comes through)."

Other writers describe scumbling techniques using “a drybrush and a loose hand” or rags.

Lesson 42 is about Drybrush – carefully dragging a brush with almost dry pigment over the painting surface to create a broken layer of fine marks.

Philip differentiates drybrush as being more controlled than scumbling. Both techniques create the impression of texture and depth by building up broken layers of paint. They can be used to achieve a blurred or soft appearance. 

I’ve experimented with drybrush in watercolour to give the impression of textures such as tree bark (see Branches, Roots, Hardwood Tree Bark, Conifer Tree Bark, Wood Grain, Volcanic Rock and Silver Birch).

In watercolour you are helped if you use a rough paper because the brush catches and leaves paint on the ridges, but not in the valleys. I am finding it trickier with acrylics because I am painting on a smooth surface. I suspect the trick is either to use a rougher surface or to roughen the surface with an unevenly applied gesso or impasto layer.

In the picture at the top of this post, I started off with scumbling and progressed towards drybrush in later layers, particularly on and around the boats.

Philp suggested experimenting with a dark ground.

I like the effect of the white pencil drawing on the umber background. I nearly decided this was finished.
