B+W 499 F-Day
This light-violet filter eliminates the unpleasant blue-green
color tint produced by daylight films illuminated by fluorescent
tubes. Filter factor is approx. 2.
B+W 415 [Wratten 2B] [Schott GG 400]
This colorless ultraviolet absorbing filter is used to eliminate
haze from ultraviolet rays and possible fluorescence from the
lens cement. Used for high-altitude photography. Filter factor
is approx. 1.
B+W 420 [Wratten 2E] [Schott GG 420]
Due to the slight yellow coloring of this filter, it is designed
for aerial photography with black and white film. Filter factor
is approx. 1.2.
B+W 470 [Schott BG 18]
This filter is used to differentiate reproductions of green tones
in reproduction photography. It may also be used to create the
effect of haze. Filter factor is approx. 2.
B+W 486
This UV/IR cut interference filter completely blocks the often
unwanted UV and IR radiation. It is especially recommended for
CCD applications where digital image sensors have not been fitted
with an IR protection filter. Further applications: video films,
digital and conventional b/w or color photography as well as
technical applications.
B+W 403 [Schott UG 1]
Although this dark-violet filter transmits a small amount of
visible light, it completely blocks wavelengths longer than 410nm.
Its application is in UV-reflection photography and for the front
of UV emitting illumination in UV-fluorescent photography. Depending
on the film, the filter factor is between 8 and 20.
B+W 489 [Schott KG 3]
This filter is frequently described as a heat absorbing filter
because it lets the visible spectral range pass while the infrared
rays from 780nm are strongly blocked. It is often used to protect
IR-sensitive CCD sensors or in illumination systems.
