Object Drawing Lessons
This lesson teaches tonal shading of a simple heart shape using a single light source. You will define a shading convention, build a value scale, and apply light, mid, and dark tones to create form. The heart is treated as a rounded, slightly convex form with a top cleft and a pointed base. All numerical values are hypothetical examples; measure your own paper and tools. The convention is explicit: light comes from the upper left at about 45 degrees, shadows fall to the lower right, and the heart's surface is smooth and matte. Letter styles and handwriting vary; this lesson focuses on tonal control, not a single correct contour.

Set the light source and value scale
Draw two arrows outside the heart: one pointing from the upper left toward the heart, labeled LIGHT, and one pointing from the lower right away from the heart, labeled SHADOW. This fixes the direction for every mark you make.
Create a five-step value strip on scrap paper. Label steps 1 to 5 from lightest to darkest. Step 1 is the paper white; step 5 is your darkest pencil pressure without tearing. Steps 2, 3, and 4 are evenly spaced between them. Test each step by filling a small square and comparing neighbors.
The heart's surface is treated as convex: the upper-left lobe catches the most light, the lower-right lobe and the base fall into shadow, and a soft core shadow sits along the lower-right edge. A narrow reflected-light band may appear just inside the darkest edge, but keep it subtle.
- Draw the light-source arrows and label them.
- Make a five-step value strip and label each step.
- Draw a heart outline with a top cleft and a pointed base.
- Mark the lightest area on the upper-left lobe and the darkest area on the lower-right edge.
Apply tones in layers
Work from light to dark. First, fill the whole heart with step 2 using light, even strokes. This establishes a base tone and prevents white gaps later.
Next, add step 3 to the lower-right half and the base, following the heart's curve. Keep the upper-left lobe at step 2. Blend the boundary with light circular strokes so the transition is gradual.
Then add step 4 along the lower-right edge and under the top cleft. Finally, place step 5 only in the deepest shadow near the base and the lower-right edge. Check your value strip: the darkest heart tone should match step 5, and the lightest should match step 2.
- Fill the heart with step 2 as a base.
- Add step 3 to the lower-right half and base.
- Blend boundaries with light circular strokes.
- Add step 4 along the lower-right edge and under the cleft.
- Place step 5 only in the deepest shadow areas.
Refine edges and check consistency
Keep the outer contour soft on the shadow side and slightly sharper on the light side. Do not outline the heart with a dark line; let the tonal contrast define the edge.
Check that every shadow direction agrees with the arrows. If a dark patch appears on the upper-left lobe, lighten it with an eraser or add step 2 over it. If the lower-right edge is too light, add step 4 or 5.
Use a clean sheet of paper under your hand to avoid smudging. Compare the heart to your value strip under the same lighting you used to draw.
- Soften the shadow-side contour and sharpen the light-side contour slightly.
- Remove any dark marks on the upper-left lobe.
- Deepen the lower-right edge if it is too light.
- Compare the finished heart to the value strip.
Worked example
A heart is drawn with light arrows from the upper left. The upper-left lobe is filled with step 2, the middle with step 3, and the lower-right edge with step 4. The base has a small step 5 patch. Describe the next check and one correction if the lower-right edge looks too light.
Worked answer
Check the lower-right edge against the value strip. If it looks too light, add a layer of step 4 or a small step 5 patch along the edge, keeping the transition gradual. Do not darken the upper-left lobe. Recheck that the darkest marks are on the lower-right edge and base, consistent with the upper-left light arrows.
Four practice exercises
Exercise 1
Draw a heart about 6 cm wide with light arrows from the upper left. Fill the upper-left lobe with step 2, the middle with step 3, and the lower-right edge with step 4. Add a small step 5 patch at the base. Describe where you place the darkest mark and why.
Show answer and check
The darkest mark (step 5) goes at the base and along the lower-right edge, because those areas face away from the upper-left light source. The upper-left lobe stays at step 2.
Why: The light arrows from the upper left mean the lower-right side and base receive the least direct light. Step 5 is reserved for the deepest shadow, not the whole shadow side.
Check: Compare the heart to the value strip: the upper-left lobe should match step 2, the middle step 3, and the lower-right edge step 4, with step 5 only at the base. Check that no step 5 appears on the upper-left lobe.
Exercise 2
A heart is shaded with light arrows from the upper right. The upper-right lobe is step 2, the middle is step 3, and the lower-left edge is step 4. Identify one mistake if the lower-left edge is actually lighter than the upper-right lobe, and state the fix.
Show answer and check
The mistake is that the shading contradicts the stated light direction. The fix is to lighten the upper-right lobe to step 2 and darken the lower-left edge to step 4, keeping the arrows labeled upper right.
Why: With light from the upper right, the upper-right lobe should be lightest and the lower-left edge darkest. If the lower-left edge is lighter, the tonal pattern is reversed.
Check: Trace each arrow to the heart and confirm that the lightest area is on the arrow side and the darkest area is opposite. Compare both areas to the value strip.
Exercise 3
Draw a heart with light arrows from the upper left. Use only steps 2, 3, and 4, and include a narrow reflected-light band at step 2 just inside the lower-right edge. Explain why the reflected-light band must not be step 1.
Show answer and check
The reflected-light band stays at step 2 because it is a subtle bounce of light, not a direct highlight. Step 1 is reserved for the paper white or the strongest direct light, which is on the upper-left lobe.
Why: Reflected light is weaker than direct light. If the band were step 1, it would compete with the main light area and flatten the form.
Check: Compare the band to the upper-left lobe. The band should be darker than or equal to the lobe, never brighter. Check that the band is narrow and sits inside the step 4 edge.
Exercise 4
Draw a heart with light arrows from the upper left. Shade it with at least four values, then write one sentence explaining how your darkest value agrees with the arrows. Include a check for whether the heart edge is defined by tone rather than a dark outline.
Show answer and check
The darkest value sits on the lower-right edge and base, opposite the upper-left arrows. The heart edge is defined by the contrast between the shaded heart and the lighter background, with no heavy outline.
Why: A consistent light source places the darkest tones away from the light. Defining the edge by tone keeps the form rounded and avoids a flat, outlined look.
Check: Look at the heart from a short distance: the edge should be visible through value contrast, not a drawn line. Confirm the darkest area is opposite the arrows and matches step 4 or 5 on your strip.
Common mistakes
- Shading the upper-left lobe darker than the lower-right edge. Recheck the light arrows. Lighten the upper-left lobe to step 2 and darken the lower-right edge to step 4 or 5.
- Using only one tone across the whole heart. Build at least three distinct values: step 2 on the light lobe, step 3 in the middle, and step 4 or 5 on the shadow edge.
- Outlining the heart with a heavy dark contour. Erase or lighten the outline. Let the tonal contrast between the heart and the background define the edge.
- Making the reflected-light band as bright as the lightest lobe. Keep reflected light at step 2 or 3, never step 1. It should be subtle and narrower than the main light area.
Self-check rubric
- Light-source arrows are drawn and labeled consistently with the shading direction.
- A five-step value strip is present and labeled.
- At least three distinct values appear on the heart: light, mid, and dark.
- The upper-left lobe is the lightest area and the lower-right edge or base is the darkest.
- Transitions between values are gradual, not abrupt, except where a crisp edge is intentionally chosen.
- No heavy dark outline defines the heart; tonal contrast defines the edge.
- Reflected light, if present, is subtle and not brighter than the main light area.
- The heart shape is recognizable with a top cleft and a pointed base; slight asymmetry is acceptable.
Questions and answers
Do I need a specific pencil grade?
No. Use any pencil you have. The five-step value strip is based on pressure and layering, not on a particular grade. Test your own tools to find step 5 without tearing the paper.
How large should the heart be?
Any size that fits your paper with room for the arrows and value strip. A hypothetical example is a heart about 8 cm wide and 7 cm tall on A4 paper, but measure your own paper and choose a size that leaves margins.
Can I use a different light direction?
Yes, but keep it consistent. If you choose upper right, reverse the shadow side and label the arrows accordingly. The rubric checks consistency with your stated direction, not a single universal direction.
What if my heart shape is not perfectly symmetrical?
Hand-drawn hearts vary. The lesson assesses tonal control and light-source consistency, not perfect symmetry. A slightly uneven heart is acceptable if the shading follows the form and the arrows.
