B+W 1102776 49mm Basic IR Black 093 Filter

The B+W 49mm Basic IR Black 093 filter is a specialized infrared pass filter designed for photographers who want to explore the creative possibilities of infrared imaging. By blocking virtually all visible light and transmitting only infrared wavelengths, this filter transforms ordinary scenes into surreal landscapes — green foliage renders as bright white, skies turn dramatically dark, and contrast between organic and inorganic materials becomes strikingly pronounced. These effects are unique to infrared capture and cannot be fully replicated through software processing alone.

The filter features a black knurled metal mount that provides a more secure grip than smooth-edged alternatives, making it easier to thread on and off in the field. B+W includes a QR code on the packaging for authenticity verification, ensuring you receive a genuine product. At 49mm, it is compatible with a wide range of compact, mirrorless, and smaller DSLR lenses, and B+W rates it for use down to 24mm focal lengths on full-frame bodies without introducing vignetting. Photographers should note that because the filter is visually opaque, all framing and focusing must be completed before the filter is attached, or handled through live view with extended exposure times. A sturdy tripod is essential, as unmodified cameras typically require exposures of several seconds or longer to gather sufficient infrared light.
