Last night we continued exploring Line through a series of drawings addressing cross-contours, continuous line, scribble, mass and negative space. The important distinctions to remember are 1. line drawings address the structure of form and 2. scribble and mass techniques address mass and volume. In addition, the latter address value changes in light because they are essentially tonal drawings.
Cross-contours address the contours moving across and around a form rather than the outside edges. "Accents" in the line quality may suggest a change in the structure as planes advance and recede as well as addressing the way light falls on the form.
Continuous Lines address the structure and volume of a form by creating an armature or skeleton with vertical and horizontal cross-contours.
Scribble Gesture addresses the mass and weight of a form as well as the location of a light source.
Mass Gesture like Scribble addresses the mass and volume of an object. Because it is a tonal technique, the categories of light are illustrated as well.
Negative Space and/or shapes are the areas around and within the forms. In the case of the arrangement above, the objective is to "suggest" the gourds by drawing the shadows, receding planes and passages between the objects.
