In a dry brush stroke the paint covers the whole surface and no rough texture appears. What is the correction?

Correct answer: Remove excess moisture and paint then use light pressure

Dry brushing depends on a small amount of relatively dry paint and light pressure. The bristles then catch mainly on the raised or textured parts of the surface, leaving broken marks rather than a solid coat. Option A is correct because removing excess water and pigment restores this effect. More water, heavy pressure, soaking, or dipping to the ferrule would make the stroke wetter and more opaque, so those choices contradict the technique.
