About B + W 77 Infra-Red Filter
For photographers seeking to explore the captivating world of infrared photography, the B & W 77mm Infrared Filter # 093 (87C/RG830) is an essential tool. 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.

Questions & Answers
Questions about this item:
Shopper (sorry thick) Does anyone know how thick the glass on this filter is? Thanks.
JERRY W This filter is surprisingly thin. I just compared it to my B&W polarizing filter, and it is much thinner than the polarizer. I also compared it to a UV filter, and it is not much thicker than that. It is much thinner than I expected.Just realize that you have to focus and compose your photo before using the filter, because it is black.....you cannot see thru it.
PETER L. S The mm given apply to the circumference or width of the fullters , not its thicknness, I would guesstimate 1/32 of an inch,
Shopper Does anyone know how this the glass on this filter is? Thanks.
PETER R Sorry, meant to say the 72 filter worked better for my camera.
PETER R The 87C blocks nearly all other light except IR so you can get stunning effects. My Nikon D300s blocks too much IR and requires long exposure times on a tripod. The 77 filter worked better for me. So in short: how well the 87C works for you will depend on the cut-off filter in your camera.
Bambi S Is this the one used for black and white IR? I was really looking for 850nm, but couldn't find any.
JEFFERY R Yes, that is how I use it. I use Nik software silver efx pro in Aperture for the black and white conversion. You can shoot in the middle of the day and pix can be better due to more ir light. If you use a standard digital camera your exposure times will be longer than if you convert it as I did with my two D200s to full spectrum(IR/UV) by life pixel. They also do IR only conversions. Full spectrum conversions allow UV, IR or both, but take a little more post processing, just put on the filter to block what ever wave lengths you don't want. Live view cameras work even better, you don't have to search for the correct exposure, with this filter your viewfinder is black so, I use a tripod then frame the pix and focus(which may not be accurate in IR, but easy to figure you, use manual focus), then screw on the filter and take the shot. You will then need to adjust the exposure to darken or lighten the photo. Depending on the camera you should be able to figure how far with IR and UV filter to adjust the exposure from without the filter on and use exposure compensation on your camera to make it easier. This process is easier than it sounds, so don't let it scare you. Above all have fun.
