B+W 77mm UV Black (403) Filter
B&W 77mm UV Black (403) Filter - This filter should not be confused with a traditional "UV" filter. This specialized filter is opaque to the eye and passes UV A radiation from 320-385nm. It also blocks all visible light. When used with the appropriately sensitized film, it is especially effective when used in forensics or in certain flourescent photography.
The filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming. In addition, the seal between the glass and filter ring is exceptionally strong giving the filter added strength and durability. The excellent Schott Glass used in the manufacturing of this filter is legendary and synonymous with the highest standards of filter production. It comes with a solid 10-year warranty.
- Used with appropriately sensitized films in such applications as ultraviolet reflection photography in forensics or in materials research, but also as filters on UV-emitters for fluorescence photography
- Depending on the illumination and on the film's sensitivity, it's filter factor is in the range of 8-20

Comments about B+W 77mm UV Black (403) Filter:
This filter works great with my modified 10D (glass filter). I also have a 52mm version for my Canon A620. (with the A620 use a tripod, and take a custom white balance, outdoors in sunlight is a 2-4 sec. exposure). Dont know what the other poster was talking about ? (im not sure what DSLR he was using, since even my 5D unmodified will work, although at 30 Second exposures with white balance).
