Opaque materials like white plaster are dominated by direct reflection at the surface.

Of course, plaster also absorbs light beneath its surface, but due to its fine particulate structure, most of the subsurface light is absorbed and does not re‑emit.

*For reference, subsurface scattering occurs in nearly all materials, and diffuse reflection is not determined by surface roughness. I will cover this in more detail later.

Therefore, in the case of plaster, under the same lighting setup, the contrast between light and shadow is more pronounced.

*At this point, the tonal distribution of plaster (considered an isotropic material) follows the Lambertian cosine law.

In contrast, translucent materials such as skin, marble, milk, and cheese exhibit strong subsurface scattering and re‑emission.

As a result, under the same lighting setup, their contrast is lower and appears relatively smoother.

Put simply, reflection in opaque materials is like [entering through one door and exiting through the same door].

In the case of human skin, the reason saturation increases near the terminator is also due to subsurface scattering.

Simply put, it is the phenomenon where red‑wavelength light penetrates more deeply and reflects off blood vessels in the skin, which I will also discuss when we have the chance.

Appropriately increasing the contrast along the form terminator (light and shadow boundary) can emphasize the depth and volumetric mass of a form.

It is created through the complex interplay of gradual tonal transitions, reflected light, material properties, and the overall lighting setup.

For instance, materials with high subsurface scattering, such as skin or marble, exhibit relatively soft shadow boundaries because light penetrates beneath the surface, scatters, and then re-emerges.

Conversely, materials with minimal internal scattering tend to have sharper, more distinct boundaries.

If you blindly darken the boundary without analyzing these material characteristics, marble can easily end up looking like matte plaster.

When drawing, it is often frustrating when you cannot achieve the desired tone.
드로잉을 하다보면 ‘톤’이 마음대로 되지 않아 답답할 때가 많습니다.

However, most issues with tone can be resolved by following these two principles.
그러나, 톤 문제는 다음의 두 가지를 지켜주면 대부분 해결됩니다.

First, keep your pencil properly sharpened.
첫 번째, 연필을 잘 다듬는 것 입니다.

Maintaining a consistently sharp point is more important than anything else.
연필을 항상 뾰족하게 유지하는 것이 그 어떤 것보다 중요합니다.

If the tip becomes dull, the lines will not come out as intended.
연필 끝이 뭉툭해지면 의도한 선이 나오지 않게 됩니다.

Before addressing tone, you should first examine your lines.
톤을 논하기 이전에 선을 먼저 점검해야 합니다.

Second, control the speed of your pencil.
두 번째, 연필의 속도제어입니다.

You need to coordinate the horizontal movement of the pencil with the vertical movement of your arm.
연필이 이동하는 수평방향의 속도와 팔의 수직방향 속도를 맞춰야 합니다.

If the pencil moves quickly from side to side while your hand moves slowly up and down, the tone will become darker than intended.
연필은 좌우로 빠르게 움직이는데 손이 위아래로 느리게 움직인다면 의도한 것보다 더 어두운 톤이 나오게 됩니다.

Conversely, if the pencil moves slowly from side to side while your hand moves quickly up and down, the spacing between the lines will widen.
반대로, 연필은 좌우로 천천히 움직이는데 손이 위아래로 빠르게 움직인다면 선과 선 사이의 간격이 넓어지게 됩니다.

While this may vary from person to person, rough tones are generally easier to correct, whereas tones with wide spacing between lines are unexpectedly difficult to fix.
