Welcome to Form and Value
• You will use this presentation to complete the Form and Value section of your sketchbook. So take notes!
• If you don’t finish it in class bring it home to be completed.
• It will be checked after the Thanksgiving break.
• The Charcoal Experiments page does not need to be completed.
Let it Roll withForm and Value!
How to achieve allvalues and formusing hatching,cross-hatching,
stippling, scribbling, blending,
and much more!
Form
A form is a 3-dimensional shape or object, it has the
illusion of height, width, and depth.
How can we show form?
What element of art will we use to show form?
Value• Proper shading of
shapes make them look 3-D.
• When looking at an object you must look for the darkest areas.
• Were is the lightest area.
• Is the object shiny or reflected lights (Highlights)?
• Always start where the object is darkest and lightly color the form.
• You can always go darker!
• Press less and less as you get to the lightest spot.
• Leave some areas white to show highlights.
• Keep coloring until you have a smooth tone from light to dark.
• You may want to go back with a darker value to deepen the shadow area.
Now add shadow on the ground to make your sphere look really 3-D
BLENDINGSmooth shading is accomplished by using the side of the drawing tool.
CREATING VALUE
Lets look at various ways to draw value, and in turn, create form.
HATCHINGShading with lines that all go in the
same direction.
CROSS-HATCHINGShading with lines that go in two or
more different directions.
• Two examples of value scales• Cross hatching and shading
STIPPLING
Shading with varying densities of dots.
SCRIBBLING
Somewhat random mark-making; emphasis on the density and thickness of the marks.
Too review....How can you show value?
• Shading• Hatching• Crosshatching• Stippling• Scribbling
• Value done in pin and ink using lines. The closer together the lines the darker the value appears
Chiaroscuro is an Italian Renaissance idea that was created in the 15th and 16th centuries and remains surprisingly relevant today.
The technique was initially pioneered by Leonardo da Vinci, further developed by Caravaggio, and finally perfected by Rembrandt.

Chiaroscuro refers to a strong, self-conscious juxtaposition of light and shade
which results in a stunning visual effect in a work of art.
Over the course of his career, Rembrandt consistently deployed chiaroscuro to produce some of the most visually arresting and psychologically evocative paintings in the history of art.
By way of this technique for contrasting and manipulating light and shadow, Rembrandt was able to achieve three specific effects which have become trademarks of his style: dramatic intensity, rhythmic visual harmony, and psychological depth.
Chiaroscuro is a dramatic lighting effect that applies value to a two-dimensional piece of artwork to create the illusion of a three-dimensional solid form.
This method was utilized
frequently throughout the
Italian Renaissance
Caravaggio (1573-1610) made
chiaroscuro his trademark. He
was a master at painting dark
scenes illuminated by a single ray of
light
Georges de La Tour was influenced by Caravaggio's work and focused his
attention to night scenes with their strong contrasts of light and shadow.
Rembrandt like Caravaggio used “tenebrism” in
this painting. The term tenebrism refers to a hard contrast of dark and light shades
within a painting.
Typically an artist will use tenebrism to convey a powerful
and dramatic scene. Rembrandt places the figure in the
foreground of the painting and sets her
against a dark background. This
causes an illusion of her moving into the
viewer's space creating a sense of
tension.
What to do: Using the notes you took during the
presentation complete the Form and Value sections of your sketch book. (but not the Charcoal Experiments page)
Be thoughtful about how you approach the shading and creation of form.
These two sections will be checked after the Thanksgiving break, so if you don’t complete it in class you will have to complete if during your break.
