How can we make our drawings more realistic by creating the illusion of form or 3 dimensional objects?
ASK
ASSIGNMENT PART A:
​
What is the difference between a shape and a form?
How are each achieved?
Write a definition for each in your sketchbook.
​
​
​Shape - enclosed area that is two dimensional - having height and width -can be geometric such as a circle, square or rectangle; free form, or organic. Appears flat.
Form appears to be, or actually has, height, width and depth. Suggests or has mass, volume.
Value refers to relative lightness or darkness of a color. Applying a range of values to a shape can create the illusion of volume or mass - a three dimensional form.

Want to know more about your drawing pencils? Although most of us have heard someone refer to the material within a graphite pencil as "lead", you may be surprised to learn that there isn't any lead there at all. Instead, graphite is a form of carbon and is completely safe for drawing. Graphite is produced in various grades or degrees according to the softness or hardness of the material. Different grades produce different types of marks. The grade of the pencil is usually designated on the side or the end of the pencil. For drawing pencils, this designation is an alphanumeric value. Writing pencils differ in how they are categorized and usually only feature a number. For example, a #2 pencil is a standard writing pencil - which happens to be of the same softness as an "HB" drawing pencil. Grades of drawing pencils are organized in a scale based on softness or hardness. An "HB" pencil is found directly in the center of the scale. "H" pencils feature harder graphite. (The "H" stands for "hard".) "B" pencils feature softer graphite. (The "B" stands for "black".) The number found in front of the letter reveals just how soft or hard the pencil is. In other words, a "4H" pencil is harder than a "2H" pencil while a "4B" pencil is softer than a "2B" pencil. Harder pencils produce lighter marks since less of the material is released as pressure is applied. Softer pencils make darker marks since more of the material is released. Therefore, a "4H" pencil will produce lighter marks than an "2H" pencil while a "4B" pencil will make darker marks than a "2B" pencil. The "F" pencil is similar in mark to an "HB" pencil, only slightly lighter. Like an "HB" pencil, it is capable of producing darker and lighter marks, but without any extremes. The graphite material found in an "F" pencil is slightly harder than an "HB" pencil meaning that it can stay sharp for a longer period of use. For this reason, this pencil is designated as "fine" which is why this pencil is labeled with an "F".
1. Create an 8 step greyscale using the Ebony pencil. Shift values by gradually increasing pressure during application.
To create the scale:
Place your ruler across your sketchbook horizontally. Trace each edge for the length of the scale. Place your ruler vertically across the page and trace each side for the width of each step on the scale.
Label the exercise " Greyscale"
2. Create a second scale utilizing the Graphite Sketch Pencils.
WHAT YOU SHOULD AIM FOR:
SHADE IN ONE DIRECTION
PRESSURE IS KEY!
NO VALUES REPEAT
2. Create a third scale utilizing a colored pencil.
Now try shading a pattern to create the illusion of form.
ASSIGNMENT PART B :
Let's try shading a form.
​
Assignment: Practice shading forms in class.
Drawing goals:
​
____ Start loosely - hold pencil to side, move from shoulder
​
____ Gradually and smoothly vary the pressure on our pencil to create a range of values
​
____ Evenly shade the form with consistent strokes following the contour of the form
​
____ Capture the primary highlight (white of paper, midtones, core shadow, cast shadow and reflected light.
​
____ Include table or paper edge, surrounding space values, note that cast shadows have multiple values.
ASSIGNMENT PART C :
IMPROVE
Assignment: Set Goals for Yourself.
Before moving on to another form, in your sketchbook take a moment to reflect on what you are learning.
Refer to the goals above and write
-
2-3 of the techniques that you feel very comfortable with and that are working well for you.
-
List 1-2 things that you would like to improve or focus on in your next drawing.
