B+W Grey Density Neutral 8x F-Pro

This B+W Neutral Density Grey 8x F-Pro (103) is somewhat more complicated to manufacture, it reduces light by the equivalent of three diaphragm points.

This filter is especially interesting for camcorders, when due to the great clarity the measured diaphragm cannot be adjusted, or in the case that a very small depth of field is specifically desired.

These types of filters, also called neutral density, are used to adjust the exposure to increase the exposure time and / or open the diaphragm, either for technical or creative reasons: for example, being able to fluidly record a waterfall, instead of freezing it.
