Share a set of commonly used photography light bitmaps for comparison when collecting and using them.

1. Rembrandt: also known as triangular light, originated from the lighting used by the world-renowned painter Rembrandt in his portrait paintings. It refers to the light shining from a 45 degree position in front of a character, forming a triangular spot under the eyes. This lighting method can enrich the image hierarchy, make the character's facial features more three-dimensional, and is widely used in portrait photography and film and television lighting. It is a commonly used light in e-commerce photography.

2. Backlight: Backlight can create a strong contrast between light and dark in the picture, with clear layers and texture, and can express specific emotions of the character. The disadvantage is that it is easy to form a yin and yang face.

3. Side backlight (left, right): The side backlight is located behind the main body and is commonly used as a contour light. It can highlight the outline and texture of the object, but attention should be paid to the handling of shadows to avoid being too dark.

4. Butterfly light: A butterfly shaped shadow that appears below a person's nose when the main light is set above or behind the camera. The photographer takes photos under such a light source. This lighting mode is often used in fashion photography, and because it can hide wrinkles, it is also suitable for shooting elderly people.
