Blending pen shading is primarily achieved through layering pen strokes to create transitions between different tonal values. This involves overlapping strokes closely to achieve smooth gradations from light to dark.
Here's a breakdown of the process:
-
Over Layering: The core technique involves applying multiple layers of pen strokes. This is key to blending and creating a smooth transition between tonal values.
-
Middle Tones as a Bridge: When moving from a middle tone to a darker tone, layering your pen strokes on the existing middle tone will help to blend the two.
In essence, blending with a pen involves controlling the density and overlap of your strokes to build up shades gradually and create the illusion of smooth tonal transitions.
