This high-quality filter is part of B & W's renowned trio of infrared filters, each designed with unique features to enhance your infrared photography experience.

The #093 filter, often referred to as the black infrared filter, is designed to filter out the entire visible spectrum. This feature makes it an ideal choice for use with black and white infrared films that have a sensitivity reaching up to 1000nm. The filter factor for this particular filter is determined by the film's sensitivity, allowing for a more customized and controlled photography experience.

In contrast, the #092 filter, a dark red filter, is primarily designed for black and white infrared films. This filter effectively filters out light below 650 nm, producing images of a pure red hue while optimally utilizing the relatively low sensitivity of infrared films. The filter factor for this filter ranges approximately between 20 and 40.

Lastly, the #099 filter, an orange-colored filter, is designed to block the blue and blue-green portion of the visible spectrum up to 500 nm. This feature reduces the excessive sensitivity of color infrared films in this spectral range, resulting in more evenly separated colors and preventing a blue tint. The filter factor for this filter depends upon the film's sensitivity.

Each B & W 77mm Infrared Filter is designed to enhance your infrared photography, offering a unique perspective on the world around you. Whether you're a professional photographer or a hobbyist, these filters will help you capture stunning, high-quality infrared images.
