B+W 39mm Infrared Dark Red 092 Filter
The B&W 39mm Infrared Dark Red (092 = 89B) Filter is nearly opaque. It looks dark purplish/red when held in front of a light source and blocks visible light up to 650nm. It passes only 50% of the radiation just below 700nm (thus the dark red color).
- From 730 to 2000nm, transmission is greater than 90%; this makes photographs of pure red and infrared images possible with the best utilization of the relatively low sensitivity of infrared films
- As the sensitization of infrared black and white films barely extends beyond 1000 nm, the red portion that is transmitted still makes a relevant contribution to the exposure; that is why this filter is the preferred filter for pictorial photography on IR black and white film

Comments about B+W 39mm Infrared Dark Red 092 Filter:
This filter has produced great results on my M6 with Rollei IR400 film (exposed at ISO 25). I can hold the camera and shoot at f/4 without a problem. I hear it work just as well on the M8 and M9. I had the 093 which is too opaque to hand hold, but regardless when you buy a b+w filter you're getting the very best.
