23. Are digital filters different from "normal" filters? With digital cameras, new and, in particular, smaller thread diameters are constantly coming onto the market. In this camera segment, silver-colored filters are in demand. B+W has expanded its product line by including the diameters in question, and the result was the filter series B+W Digital Pro. This filter series is specifically conceived for digital cameras and camcorders. The filter glasses correspond to those of "normal" photo filters. The B+W Type 486 UV-IR CUT filter (Transmission curve) can be characterized as specifically a digital filter. This interference filter blocks the UV and IR components which interfere with the electronic photographic medium.
