Value:
is used to show the impact of light on an object. There are three things that are important to creating value in an artwork. 1. Source of light 2. Direction of light 3. Intensity or brightness of the light.

Assignment # 1: Create a gradient Value Scale. Very 3 dimensional drawings contain around 9 values, it is important to learn how to create these values. Creating each of the nine values is about how you touch the paper with your pencil in this case. Press hard and you will achieve a low value or a # 1 tickle the paper and you will achieve a #8. How you hold your pencil is also important. I usually hold it an an angle so that a wide part of the pencil contacts the paper rather than vertical so that only the point makes a thin mark.
Assignment # 2: By now you are looking at your Gradient value scale and saying. Boy Mrs. J this value scale doesn't look very 3-D. This is because it is not an object. An object that will cause you to have to think about the direction of light and is a like gradient value scale is a Ribbon.
Start by holding two pencils about an inch apart. Draw some sort of squiggly line while holding both pencils. You may want to practice this a few times before committing to your final drawing.
Next choose a direction of light. (left or right in this case). Now number your drawing lightly to help you figure out where you will need to have # 9's and where you will need #1's. Please see the image for help with this. Then start filling in your meaning full values. Please do not put lines between your values but rather try to make them blend smoothly into each other. Do not worry about putting a shadow under the ribbon at this point.

Assignment #3: By now you have location of value down now lets do something to help you understand how shape impacts value. Not only is what value and what location important but also the shape of the values. Each form that you draw will require you to pay close attention to the shapes of the values.
Try drawing the following three curved sided geometric solids. Look at the example image to see that each shape requires a the shapes of the values to change. Draw a cone, cylinder and a sphere and apply all 9 values, place them so that they show a right or left light location and make sure that the shapes of the values are correctly matched to the shape of the object.
