Overview
The 37mm, 1/4-grade K&F Concept Black Diffusion Filter is designed to reduce highlight values while slightly lowering overall contrast. Ideal for fashion and beauty applications in both photography and video, it smooths out and softens facial wrinkles and blemishes without significant loss of detail.
Core Features
This filter uses a double-polishing process to maintain high-definition image quality. The 1/4 density allows for 84% light transmittance, offering a soft, pastel-like quality of light with balanced contrast and highlight reduction.
Build Quality
The filter is constructed with high-quality optical glass featuring 28 multicoated layers, making it waterproof, scratch resistant, and oilproof. It is encased in a slim, aviation-grade aluminum frame with machined grooves for easy handling.
