B+W 1102779 58mm Basic IR 093 Black Filter

The B+W 58mm Basic IR 093 Black Filter is a specialized optic designed for infrared photography. It works by blocking nearly all visible light and passing only infrared wavelengths, which fundamentally changes how your camera's sensor records a scene. Green foliage reflects infrared light strongly and renders as bright white, blue skies absorb it and go nearly black, and clouds stand out with dramatic contrast — the combination known as the "Wood effect" after infrared photography pioneer Robert Wood. The result is an otherworldly, high-contrast monochrome aesthetic that cannot be replicated with standard post-processing alone.

Constructed from optical glass and mounted in a black knurled aluminum ring for a secure grip during installation and removal, this 58mm filter threads directly onto compatible lenses. B+W rates it for focal lengths down to 24mm on full-frame sensors without introducing vignetting, making it suitable for wide-angle landscape work. Because virtually no visible light passes through, exposure times increase dramatically — often into the range of several seconds or more — so a tripod is essential. Focusing should be done before attaching the filter since autofocus systems cannot operate through the opaque glass. Each unit ships with eco-friendly packaging and a QR code for authenticity verification.
