B+W UV 010

B+W 010 UV
(Flatter/neutral response across the visible spectrum, superior to the Hoya HMC Super)
Hoya HMC Super UV (0)

Hoya HMC Super UV (0)
(Note the attenuation in the dark blue range, making the filter notably less neutral than the B+W offering)
B+W 103 ND 0.9 3-stop neutral density

B+W ND 0.9 3-stop neutral density
(This filter takes liberty with the term “neutral”, which can be seen readily with real images)
B+W 489 infrared block

B+W 489 infrared block
(not entirely effective at blocking infrared, with its sloping “tail” into the IR band, also passes UV)
B+W 091 dark red

B+W 091 dark red
(This filter is very dark red, but allow composition through the camera’s viewfinder)
B+W 092 infrared-pass

B+W 093 infrared-pass

B+W 093 infrared-pass
B+W 403 Ultraviolet-pass

B+W 403 Ultraviolet-pass
(A poor choice for UV due to the huge infrared “leak” in the 700-840nm range)
