We see dark to light and all the gradations in between, and the gradations or shades are what we call values. The artist finds the value, the darkness or lightness of a surface, and takes that information to render the form. This is what gives size, shape, and depth to the form of the subject. We are all familiar with shadow and light, but it is the gradations of different value levels that give us a sense of form.
There are three things to learn in this sub-unit
WHAT Value is
SHADING with VARIOUS MEDIA [APPLICATION OF SKILL]
OBSERVATION OF Light and shadows on forms
WE SIMPLIFY OUR VALUES TO A 7 POINT VALUE SCALE
Refer back to your contour line drawing of the Styrofoam cups.
Using Charcoal, add in the shadow areas of your drawing
Use a finger/tissue, blend out the shadow to form a gradation to the lighter areas. Use white charcoal if needed to bring some lighter areas back
IMPORTANT: DO NOT USE STRAIGHT MARKS - THE CUPS ARE CURVED, SO YOUR MARK MAKING SHOULD BE CURVED AS WELL!
You can add in shadows on the table top.
Notice how a sense of depth is created on a flat surface through the use of dark and light values!
Materials: Black paper, Ruler, Pencil, White charcoal (or white pastel),
Value Scale: Using your pencil and ruler, create a 7-step value scale on your black paper. This will help you understand the different shades you can achieve with your white charcoal. Practice creating each value, from the lightest to the darkest, by varying the pressure you apply.
Draw a rectangle on your paper.
Place your ruler on the rectangle and trace along both sides with your pencil. If your ruler is too wide, use a strip of paper instead.
Fill in this first strip with your white charcoal, applying heavy pressure to achieve the lightest value.
Now, carefully reposition your ruler. Trace along the ruler's edges again.
Fill in this second strip with the next lightest value, using slightly less pressure. Notice how the contrast creates a distinct line between the two values.
Repeat this process five more times, each time moving the ruler and using lighter pressure to create progressively darker values.
Think about: How does the white charcoal interact with the black paper? How does varying the pressure change the appearance of the white?
This exercise will help you develop control over your white charcoal and understand how to create a range of values on a dark surface to create depth. Have fun!
Using spheres, we are going to pratice our value application using a variety of media, starting with something we are familiar with - graphite..
lets start with looking at graphite pencils and value - watch the introduction to graphite video and make a range of marks in your visual diary to see teh difference between the different grades of pencils. If your teacher has an 8B pencil - give that a go...
What to avoid when shading - watch the video.....
Watch the Value gradation scale Video and have a go at creating a well shaded vale dradation and value scale like below
When shading with value, avoiding hard outline edges can create a more realistic and three-dimensional appearance. Hard outlines tend to flatten an object and make it look less natural. In real life, light and shadow interact with objects in a way that rarely creates sharp, defined lines. Instead, transitions between light and shadow are usually gradual and subtle.
Here are some additional reasons why hard outlines should be avoided when shading with value:
Realism: Hard outlines can make a drawing look cartoonish or artificial. By blending values smoothly, you can create a more realistic and believable image.
Depth and Dimension: Gradual transitions between light and shadow help to create a sense of depth and volume. Hard outlines can make an object look flat and two-dimensional.
Form and Shape: Soft edges allow the viewer's eye to follow the contours of an object more naturally, helping to define its form and shape.
Focus and Attention: Hard outlines can distract the viewer's eye and make it difficult to focus on the overall composition. Soft edges create a more harmonious and unified image.
Techniques to Avoid Hard Outlines:
Blending: Use blending tools like blending stumps to smooth out the transitions between values.
Layering: Gradually build up values in layers, starting with light tones and gradually adding darker ones.
Hatching and Cross-hatching: Use hatching and cross-hatching techniques to create a range of values without relying on hard outlines
Varying Pressure: Vary the pressure of your pencil to create different values and soft edges.
By avoiding hard outlines and using these techniques, you can create more realistic, three-dimensional, and visually appealing drawings.
Using spheres, we are going to pratice our value application using a variety of media, starting with something we are familiar with - graphite..
Now to shade a sphere. This will be demonstrated to you in class - if you are away you can watch the video and give it a go.
no dark lines until it looks correct - if you need to erase your drawing= too dark!
The secret is layers layers, blend blend blend. You will need a worksheet to practice on ....
Layer and blend colours lightly first and then “burnish”
Use lighter version of main hue for highlight.
Dark cool colour for shadow.
Cast shadow = colour of table + cool dark hue
USE THE WORKSHEET TO SKILL BUILD AND THEN APPLY TO A FULL SIZE SPHERE THE SAME AS YOU DID FOR YOUR OTHER MEDIA
You are to create two value study drawings. These are designed to develop your observation and shading skills
Scroll through the Slideshow on Positive and Negative space to the left, Then watch the video on shading Positive negative below. After Watching the video, select a page from the negative space value reference PDF to render as a drawing. You need to pay attention to both the positive and negative space during the contour line drawing phase... erase heavy lines BEFORE shading
2.Paper Twist
tape one end of strip of paper to a piece of board. twist the paper until it starts to curl up. Tape the end down and render this sculpture as a graphite drawing in your visual diary. Watch both the slideshow and video on paper twist on this page.
Extension - Draw like Ed Ruscha. Using a strip of paper, bend it into a word or your name. photograph it in strong lighting and then render it into a greyscale drawing
