Blind
Contour Line: Blind contour line drawings are done without looking at
the paper. The eye is focused on the subject and follows changing structural
planes of the object while the hand follow with the pencil on paper.
These drawings are intended as exercises for the eye, they are usually
distorted and sometimes even unrecognizable.
Quick Contour Line: The quick contour line technique is a variation
of the basic contour drawing. It is an exercise requiring less time
for each drawing. You may look at your drawing more frequently than
in a slow contour. The inspection of forms, however, is just as intense.
A single, incisive line is the goal. However, the movement of the line
is faster, less determined. In quick contour you are trying to catch
the essence of the subject.
Contour
Line: Contour line is a single, clean, incisive line. Contour line defines
edges. It is, however, unlike outlines, which states only the outside
edge of an object. Contour delineates the edges of planes. The quickest
way to understand the difference between contour line and outline is
to look at the image provided. Outline makes the hand appear flat; it
simply differentiates between positive and negative shape. The contour
drawing emphasizes the hand's three-dimensional appearance. If you were
drawing a pencil using contour line, you would draw a line at the edge
of every shift in plane. The ridges along the length of the pencil,
the juncture of the metal holder of the eraser and the wood, the insertion
of the eraser into its metal shaft - all are planar changes that would
be indicated by contour line.
