On the relationship between light and shadow and sketch in product painting

The relationship between light and shadow drawing and sketch is an important part of product refinement.

Light and shadow drawing refers to transforming sketch graphics into images with three-dimensional and light and shadow effects by adjusting hue, light and shade, curves, etc. It is a form of painting, which can reflect the light and shadow of objects from different angles and bring more stereoscopic visual effects to images.

The five tones of sketch refer to the basic elements of sketch, including lightness, saturation, color temperature, brightness and contrast. Brightness refers to the brightness of the luminous object in the image, which can be adjusted to make the image softer and rounder; Saturation refers to the color saturation of an image.

The color density of the image can be adjusted to make the image more vivid; Color temperature refers to the hue of the image, which can be adjusted to make the image more natural; Brightness refers to the brightness of an image, which can be adjusted to make the image clearer and brighter; Contrast refers to the contrast of an image.

You can adjust the contrast of the image to make it clearer and more prominent. By adjusting the five colors of sketch, the image can be more harmonious, more delicate and more realistic, thus playing a greater role in light and shadow drawing. When drawing light and shadow, we should adjust different tones according to different objects, and finally achieve the best drawing effect.

Only by combining the adjustment of the five tones of sketch can the image be more realistic, with depth and three-dimensional sense.
