Transcript of Gradation- Charcoal

Gradation Primary 6 Value
System Week 1 - 2 Charcoal wHY DO WE NEED TO
LEARN TO BUILD A TONAL SYSTEM? In order to reach this modelling, it is necessary to use the various tonal values correctly

The right combination of constrast between light and shadow gives volume to the elements. The right way to
hold a charcoal. Control the charcoal pencil by holding it either straight up for more defined lines or more on its side for lighter lines for shading purposes. 1 2 Lesson
Progression 3 4 When? About Charcoal Obtained by burning selected woods in anaerobic conditions.

One of the oldest art materials.

Used by our ancestors to draw on cave wall. High tendency to "dust-off"


Difficult to erase mismarks on a paper Sensitive

Spontaneous

High constrast colour Charcoal has the ability to go rich dark black.

Give you more pop and drama by including areas of white, vaious shades of gray, as well as areas of black in your composition.

Low constrast composition --> Subtlety is what you are going for. Charcoal Drawing supplies Compressed charcoal

Comes in soft, medium and hard.(soft is darker and hard is lighter)

Has more staying power Kneaded Eraser

Soft , easer that you can squeeze into any shape. (good for creating subtle gradations). Vine Charcoal Stick
This is uncompressed charcoal that is easy to erase Paper towels

Good for blending large areas and "erasing"vine charcoal sketches. Gum/white erasers

Harder erasers (good for erasing the most charcoal to reveal white highlights. Blending stump

Good for blending smaller detail areas. cOMMON MISTAKES Messy Shading Well Shaded Smooth Texture
Gradual transition between values
Range of lights and darks Hurried
uneven
Clearly see the pencil lines Clearly see a line that defines the different values.

No smooth transition between light and dark Smooth Texture
Gradual transition between values
Range of lights and darks Well shaded Abrupt transitions Well Shaded Timid Shading Smooth Texture
Gradual transition between values
Range of lights and darks Nice smooth transition
drawing is too light
Washed out,flat looking drawing Entire sphere shaded in midtones.
Very flat
look dull and drab Smooth Texture
Gradual transition between values
Range of lights and darks Smooth Texture
Gradual transition between values
Range of lights and darks Well-shaded Shading in different directions More subtle mistake
Look closely -->smooth and patch of work. Shading done in different directionsl horizontal, vertical diagonal
Look messy With HB value, it will never get the rich shadows
Press dark? wont go hard.
Paperfiber will be affected. Improper tools Smooth Texture
Gradual transition between values
Range of lights and darks Well-shaded Grey Shading Well shaded Points to take note of

1) For shading , it is essential to maintain the same pressure all the time .

2) move at the same pace in order to achieve a uniform texture.

3)Locate where is the darker zone where is the lighter zone, as well as the number of intermediate values.

4)The comparision is always based on the concepts” one is darker than the other” or one is lighter than the other.”

5)A progressive shading must be rendered, with smooth transitions between shading. Wash your hands after working with charcoal
Never put them in your mouth. 1) Dragging lengthwise
-- Wide and thick stroke Shading with charcoal 2) the amount of pressure you apply willl determine the darkness or luminosity 3) Tones can be lighten by rubbing
