And by reducing the red saturation, weakening the color with ruddy skin color, reducing the orange saturation and increasing the orange brightness, the character's skin color is transparent.
The role of rendering in video production is:
Different light sources have different color temperature properties, and different color temperature properties will produce different color effects. According to this feature, we can use color film to achieve the effect.
Yellow, blue, red and other color films will directly change the color properties of light and help us express the shooting theme.
And in order to improve the theme of the picture, you can try to use a small area light source with low color temperature to fill the light for the characters.
How do people take pictures in the case of backlight?
1, lens interactive backlight: Although portrait backlight can take textured photos without facial expressions, it can also make backlight interesting if it is matched with facial expressions that interact with the lens, such as smiling and scissorhands.
2, side backlight: the backlight itself is very soft and can express emotions well. If the portrait is backlit with the photo pose of the upper face, let the light hit the hair tips and facial features to increase the halo effect. It looks more stereoscopic and beautiful.
