Negative drawing is leaving the black paper blank where shadows are needed and add the lighter values with white charcoal to create the light areas & highlights.

A block-in is a light sketch of your whole composition before any details or shading are done to make sure it’s placed correctly on the page and that the proportions and distances are accurate.

We will be looking at this NOT as a glass container, but as lines, shapes, values, and edges only. Stay away from the preconcieved idea of what the glass is - and pay attention to what you see, especially the reflections and highlights.

Use paintbrush to add subtle areas of value

Image A: On a scrap sheet of black drawing paper (very important, don't do this on your final drawing), draw a dense patch of light value to create some white charcoal dust.

Image B: Load up your paintbrush with charcoal dust by brushing it over the value in a back-and-forth motion.

Image C: You can now use the paintbrush as a drawing tool to create marks and 'washes' of smooth, subtle value.

Block in the subject matter with light, sketchy lines, because you will modify them several times while you define your form.

LIGHTLY draw out the outlines of the shapes that will become the lighter values and highlights of the drawing.

Filling in the light shapes with a flat value will help you judge how accurately you have drawn the highlight shapes.

Work from larger, simpler shapes to smaller, more intricate ones. Working 'from general to specific' and 'from large to small' will greatly improve the accuracy of your drawings.

To smooth out white charcoal, use a soft paintbrush in a back-and-forth motion. This pushes white charcoal dust into the pores of the paper, creating a flatter value - less 'graininess'.

Look for and draw in the lightest values on the container.

Look for and erase out the darkest values of the container.

Refine the half-tones, or middle values, and making sure that the range of middle values is evident in the drawing.

Focus on the variety of values and edge qualities, from sharp to soft.

Begin highlighting the surface with the white charcoal pencil, and then smooth out the marks using the paintbrush. Note that the paintbrush does not always create a perfectly even value. Smooth out uneven areas created by the paintbrush with the white charcoal pencil, and repeat if neccessary.

Team up with a partner

Your partner will be holding the dark background paper

Take at least 10 photos of your glass, using different angles & compositions - (Angled, close-ups, upside down glass, from the bottom, from the top, straight forward) make sure you capture the reflections! This is what will make your drawing interesting.

Switch with your partner so they can also get their photos.

Post your 3 best photos - this is the formative graded exercise.

You will choose the strongest, most interesting composition from 1 of these 3 photos
