Step 3: Developing color depth and form

Continue building the rock forms and color depth. Next, begin painting in the rock textures and shadows using raw umber and a glaze medium such as stand oil diluted with turpentine (approximately 2 stand oil to 1 turpentine). If you prefer, you can use just linseed oil.

Glaze the colors stronger for dark areas and weaker for lighter ones.

Glazes are usually applied slightly deeper than needed and then softened back to the desired depth by wiping or stippling with a soft brush, cloth or finger. Both opaque and glaze techniques can be used in a painting as shown in this exercise.

Notice the illusion of transparent water beginning to develop as you paint in the dark areas on the rocks. Rocks are usually darker around the waterline and where they are wet. Use the brush handle and scrape out the small light pebbles. Allow painting to dry before proceeding to step 4.
