How to build light and shadow in charcoal

Light and shadow can bring a new level of artistry and storytelling to our
charcoal drawings. My professional person work as an animation artist calls for a strong agreement of lite and shadow. Indeed, information technology’south one of the most important art techniques

in my toolbox. I need to have a technical understanding of how low-cal works so that I can requite a believability to the scenes that I create.

Passages of light and shadow can exist designed to give special emphasis to each moment of a film. Vibrant contrasts of light tin convey an exciting energy, while nuances of lite can create subtle mood changes.

Long before I began working in motion-picture show, my understanding of light developed through observational cartoon. The study of low-cal on grade has been key to everything I do equally an artist. In this workshop we’ll explore
how to draw
a portrait in charcoal, using light and shadow to convey course.

01. Institute where straight light falls

Compare the egg diagram with the generic light-and-shadow head (beneath). Discover how each major protuberance of the head is like a mini version of our simple diagram. For instance, have a look at the olfactory organ: it has a highlight, halftone, core shadow, reflected lite and cast shadow.

Now analyse the mentum, the lower lip, the cheek and the forehead: each has the same quality of light and shadow. Even the center, every bit it protrudes out of its socket, tin can exist treated the way a elementary sphere reacts to light. When you learn to observe these simple relationships of lite and shadow, rendering grade becomes relatively straightforward.

02. Observe the ambient light

Mutual sources of ambient light are indirect window lite or outdoor lighting on an overcast mean solar day. This type of lighting is potentially fifty-fifty simpler than straight light: forms bend away from the light source into shadow, and cast shadows are soft edged and diffuse.

Considering electric lighting is relatively recent, there’southward a long tradition of portraits painted under ambient light sources. Standard practice was to place the portrait subject in the light of a north-facing window, which would maintain a consistent level of illumination for many hours during the day. Even today, many portrait artists adopt the soft quality of ambient lighting for a sensitive rendering of their subjects.

03. Simplify what you meet

The next important simplification is to organise the head into clear, committed masses of light and shadow. As a cartoon instructor I’ve found that new students almost e’er look at individual contrasts of anatomy every bit they draw, rather than noticing the bigger, simpler masses of low-cal and shadow. The results are bumpy, overwrought beefcake that starts to look more similar a sack of walnuts than like a human head.

Then before we ever start rendering the nuances of light and shadow, I enquire students to place and commit to the simple masses of light and shadow. They also have to look for and emphasise the quality of the shadow edge. For case, cast shadows tend to have a hard edge, and turning forms tend to have a soft, blended border. If we emphasise this simple statement of lite and shadow in our portraits earlier we render nuances, we’re more likely to end upwards with potent forms and an accurate likeness.

04. Use highlights to emphasise course

Examine the highlights in the drawing of this plaster cast. See how they tend to fall at the crest of each form facing the light? The placement of highlights is critical to show turning forms. Pictured above is a simplified version of the confront to show how the highlights describe the curving forms. The highlights tend to fall on the corners between the big planes of the caput.

05. Observe where planes run across

The red-lined diagram shows the side plane and forepart plane of the cheek, with the highlight falling where they meet. It’due south the aforementioned with the nose: the highlight falls along the edge where the side plane and the forepart plane meet. Whenever you’re struggling with creating clear form in your drawings, autumn dorsum on this simple quality of highlights. Even if you cease upwardly exaggerating what you see, you’re telling the fiddling white lie to convey a greater truth.

06. Don’t draw everything yous meet

In these ii drawings, the woman on the left is primarily in shadow and the adult female on the correct is primarily in low-cal. When I was drawing the woman on the left my eyes could perceive a keen deal of value range. But I knew if I tried to render every subtlety, not only would information technology take too long merely the masses of light and shadow would be broken up and confusing. I had to decide what to emphasise about my subject and what to edit.

07. Explore unlike types of lite

I decided that the rim light on the left-paw face should be pushed into a narrow range of brightness so that I would take the residual of the value range to render subtleties on the shadow side of the face. The value chart below the drawing shows the suspension between light and shadow. The outcome is a clearer, more committed drawing.

For the right-hand drawing, I was interested in the subtleties of character and form created by the halftone lights. This led me to make the determination to push all the shadows into a very narrow dark range, as seen in the lower part of the value graph. That pick opened up a wide range of tone to render strong form and character in the light.
