Graphic design theory: PS light and shadow performance adds artistic effect to photos – Design knowledge

Graphic design theory: PS light and shadow performance adds artistic effects to photos. Light and shadow technology is widely used in Photoshop. It can not only increase the authenticity of the picture, but also significantly improve the effect of the picture.
There are many kinds of light and shadow production in Photoshop, and the production methods are also different. Below we briefly introduce several methods of expressing conventional light and shadow effects, and we will explain them in detail later when we have the opportunity.
 1. Side light makes the picture more dynamic
Side light is generally used a lot in indoor photo processing. It can make up for the lack of indoor light and use light to increase the brightness of the picture. The effect is much better than directly increasing the brightness, and can make the picture more dynamic (Figure 1, Figure 2)

Production method: Add a new layer in the layer panel, then use the selection tool to select the light route, then fill it with white, and select the “overlay” mode (or “bright light” mode, depending on the mode in the layer panel). Screen needs to be selected). Use an eraser on the edges to create a soft edge effect.
 2. Shadows make the picture more realistic
 Shadows are another way of expressing light. It is made according to the direction of light to make the three-dimensional effect of the picture stronger, and is often used in composite photos (Figure 3).
