Demonstrate how to cover the back of the paper with an even layer of graphite, using the 2B pencil.Have the students secure the black and white copy of the image, wrong side up, on the clipboard.(see below for modifications for oil pastel) Instructions for Lesson (using colored pencils) Hand held sharpeners let you control the sharpness of the pencil based on your need.Impressed lines, or indentations, can be used for creating special effects like the sunken seeds in strawberries, or the veins in a leaf.Hold the pencil perpendicular to the paper for sharper lines.A blunt point is used for a rough fill-in because it skips the valleys, and stays only on the top surface.A sharp point on a pencil turned on its side (parallel to the paper) creates a smoother texture, as it gets into all the paper’s grooves.Use the white of the paper as the ‘highlight.’.When applying color, start with the lightest color and progress to the darker ones.Try using varying pressure to test what works. Overlap each color slightly to create a smooth blended transition. Use colors that are next to each other on the color wheel. This is a great learning tool, to test various color combinations. Create a color swatch on a spare sheet.Keep in mind that every stroke will show in the final product. Always let lines’ strokes follow the contour of the object.Show at least one image of Paul Cezanne’s fruit still life paintings.red changes to red-orange, changes to orange, changes to orange-yellow, etc. Switch to the colored image and remark at the way the colors vary in response to the same ‘shadows.’ Look for these colors on the color wheel, especially if they change to the colors lying immediately next to each other: e.g.Students may try this on a piece of scrap paper to view the way shading controlled. This can be drawn by lightening the pressure of a pencil on the paper gradually.
Explain that the shades of gray that appear between the lightest and darkest areas are where the light is indirectly hitting the object. Using an overhead projector, point out the way light and shadow define the form in the black and white image.
Make one color and one black and white copy of the image for each student. It may or may not be related to a current subject of study in the other classes. Advanced PreparationĬhoose a simple form’s (ball, pear, apple, strawberry, green pepper, cup) image. Light travels in a straight line and as it shines on a form it is affected by surfaces turning away from the light. They will then use color to recreate the form in their own drawings. Students will use the images to ascertain how light and shadow define the contours of the simple form.
