B+W 49mm Neutral Density 110 [3.0] Uncoated Filter

With a light intensity reduction of ten f-stops, this B+W Neutral Density Filter has a slightly stronger warm tone than the ND 106. Its principal field of application is the observation and documentation of industrial processes with extreme brightness, such as steel furnaces, incinerators, glowing filaments in halogen- and other bulbs. The filter factor is 1000x.

B+W gray filters are available in a number of values (1, 2, 3, 6 and 10 f-stops) and permit wide aperture even when it is very bright for low depth of field and an interplay of sharpness and blur and/or long exposure times for motion blur or wiping effects (speed emphasis or flow of water). They also permit “normal” time values and f-stop values when the film sensitivity is too high for the prevailing light. Gray filters with higher density (3 to 10 f-stops) are also used for technical photography, e.g. shots of lit lamp filaments, of combustion processes and procedures in melting ovens as well as for astrophotography.
