What is the light that illuminates a character's face?

Light that illuminates a person's face is called soft light.

Soft light lamp refers to a photographic lamp with soft light and no obvious shadow, which is suitable for reflecting the shape and color of objects and gives people a soft and delicate feeling. You can soften the light of the flash to make the photos look more natural.

Its principle is to transform the direct light of rigid flash into soft diffuse light through high-temperature resistant translucent plastic, eliminate annoying high points on subjects such as portraits, and make your photos as beautiful and natural as those taken in a photo studio.
