Core Principle: By physically reflecting light, natural light is redistributed. Without power supply, scattered light and sunlight in the environment can be precisely directed to the dark areas of the subject. This solution at a low cost addresses issues such as dark faces in backlighting and heavy shadows from top light. It is an extremely cost-effective lighting tool for outdoor portraits.

Common Types: The mainstream type is a five-in-one folding model, featuring five functions - white, silver, gold, black, and soft light. Different surfaces are suitable for different outdoor light scenarios. When folded, it has a small size and can be easily stored in a photography bag.

Main Sizes: 60cm is the ideal portable size, balancing both single-person half-body portrait lighting and portability; 80-110cm can cover full-body portraits, and larger sizes above 120cm can achieve more uniform large-area lighting.
