1. Understanding Line
From simple to complex. . .

2. What is a line?
In Geometry, line is defined as an endless series of dots: or the path of a moving dot

3. What is a line?
In drawing, a line is a mark created by moving a tool across any surface.

4. What is a line?
Artists use lines to control eye movement and lead your eyes through visual imagery

5. Line
Lines are everywhere; we use them to create letters in written words, we use them to create symbols that represent numbers. Lines are used to draw pictures that represent the world around us.
You see lines everyday.

8. Line?
A Dimension is the amount of space an object takes up in one direction
Typically, a line is considered “one-dimensional” … it would represent length
A line does have width as well as length, but if the width is smaller in comparison, then we would still consider it a line

9. Four Basic Types of Lines
Horizontal
Vertical
Diagonal
Curved

10. The Obvious STRAIGHT-CURVED-(Angle – Degree of Curve)
SMOOTH-JAGGED (Rough)
LONG- SHORT
THICK-THIN

11. Perceived Lines
Some lines that we perceive do not actual exist. For example, the edge of this form creates the idea of a line

12. Perceived Lines
Line is used to define the outside edge of the object

13. Line
When we draw a ball using a line to represent its outside edge. This is called an outline.

14. Lines can create 2-D shapes
Lines around a shape are Outlines

15. Lines can also create or imply 3-D Form
Lines within a shape are Contour and create illusion of 3-D Form

16. Lines can be implied . . .

17. Implied Line
Sometimes, the lines or dots can be broken, but our eye will still complete the line.
Sometimes, the line is not really there but guide the eye or organize the image
This is called an implied line.

19. What different Lines express
The Expressive quality of line is the line inside the object within in the art work. For example, an image of a soldier standing tall has an implied vertical line in the stance. Each of the lines imply different meanings and expressions

20. What different Lines express Vertical lines
Vertical lines move straight up and down. They are perpendicular to the Horizon.
Vertical lines are static, or inactive; the line appears to be at rest.
A vertical line can express nobility, dignity, poise, and formality or strength
Horizon
Vertical Line

21. What different Lines express Horizontal lines
Horizontal lines are parallel to the horizon
Horizontal lines are also static.
They express feelings of rest, quiet and stability
Horizon
Horizontal line

22. What different Lines express Diagonals and Zigzags
Diagonal or Zigzag lines are active.
They communicate action and movement because they seem to be pulled in a given direction. Zigzag diagonals seem to be rising and falling.
These lines express instability and tension.
Diagonal

30. Lines can curve . . .

31. What different Lines express Curved lines
Curved lines also express activity, but the action is more graceful because the change is gradual.
The amount of action expressed is dependant on the degree and direction of the curve.
Curved

32. The Obvious Again STRAIGHT-CURVED-(Angle – Degree of Curve)
SMOOTH-JAGGED (Rough)
LONG- SHORT
THICK-THIN

33. Curved, smooth Jagged Jagged, zig-zag straight
Looking up in amazement as Christ ascends into heaven are the twelve apostles. Kneeling with them is the Virgin, the only one to have a halo. Although few of the men can be identified, John the Evangelist is recognizable. He is the blond, beardless youth dressed in green who solicitously puts his arm around Mary. Surrounding the risen Christ are a group of Old Testament personages who either predicted or foreshadowed events of his life on earth.
The gold background, bright colors, and compact space reveal the lingering influence of the International Gothic. However, a new spirit of visual observation also can be detected. The sharp, angular folds of the drapery evoke the perception of real human forms beneath the material. Further, the faces of the apostles reveal a broad variety of human emotions.
This panel was once part of the high altar in the Cistercian abbey church of Marienfeld at Münster. At its center was a richly gilded sculpture of the Virgin and Child. Folding wings extended from this core with pictures on the fronts and backs. When the shutters were open, eight scenes -- including the National Gallery's painting -- revealed the story of Mary's life. In the closed positions, eight other subjects recounted Christ's Passion.

34. Using Line expressively
Contour line defines not only the outline but also the surface or form of an object.
A contour line creates a boundary separating one area from another.
Contour lines focus on meticulous detail.

35. LINE ON HANDOUT What is a line in Art?
Line – a series of points; an area whose length is considerably greater than its width; an indication of direction, an apparent movement. A line is a point moved or moving through space. This applies to drawing, painting, printmaking, sculpture, clay/pottery, and architecture.
Characteristics of lines: lines can be actual or implied; a line which defines an outside edge of an object is a Outline. A line which defines the surface of a form is a Contour Line.
A directional line points or moves the eye in a particular direction. Horizontal: rest, quiet and stability. Vertical: nobility, dignity, poise, and formality or strength.
Lines can be interpreted as having expressive qualities; particular qualities – thick or thin, weighty or straight, hard-edged or soft – can indicate moods or feelings.
