Photographing the sun safely has traditionally meant one of two things: building a DIY filter using specialist solar film, or investing in a dedicated astronomical solar filter system. The K&F Concept ND1,000,000 takes a different approach.
Rather than using a dedicated solar film, it’s essentially an extremely dark 20-stop neutral-density filter that reduces sunlight by a factor of 1,000,000. Designed primarily for ultra-long-exposure photography, it’s a convenient, durable, and straightforward screw-in design.
