Features: Made of durable plastic with fine workmanship, the material is ideal for light transmission, ensuring no color cast on your flash! Simply attach to your flash unit. Perfect for portrait fill-light photography on sunny days, news photography, landscape macro photography, and more. Minimal adjustments needed, except for a maximum distance reduction factor of 2.5. Avoid using the diffuser in a normal direct overhead position unless in TTL mode. A 45-degree tilt is recommended for optimal results. The film is transparent due to a specific molecular arrangement in a grid pattern at a certain thickness, allowing light to scatter and transmit. Temperature resistant up to 130 degrees with excellent flexibility. Product Function: Softens and evens out flash light through diffused reflection, reducing harsh shadows on your subject for more natural-looking photos. The high-temperature resistant transparent plastic converts the flash into soft, diffused light, eliminating bright spots on portraits for beautiful and natural results.
