Pinte

Yo! I’m assuming what you mean is being able to paint or “sculpt” the form once you’ve already established the graphic shapes of light and shadow. In summary, or at least based on how I’ve learned it: First, you need to determine which part of the object is most important, that is, where the main details will be. If you have an overexposed light source, then most of the details will be found in the shadows, and vice versa: if most of the information will be in the lit areas, then keep the shadows simple. This leads into the next part: you need a general understanding of the different aspects of light and shadow, things like ambient occlusion, ambient light affecting shadows exposed to the sky or background, core shadow, rim light, etc. It’s very important to first understand all of these properties because it becomes much easier to apply this knowledge to more complex scenarios and to paint from large forms first down to smaller, sculpted details. A lot of the time, we struggle to paint forms in greater detail because we don’t fully understand these painting fundamentals, and these fundamentals apply to everything: characters, environments, props, still life, etc. A quick example: I only added a bit of ambient light to the rock in the second image, and notice how it immediately has more form. The bluish tones in the buildings work the same way, since the sky influences those shadowed areas. Hope some of this helps! :)
