Filters for B&W films
Y48 (Y2): Yellow filter which absorbs ultraviolet,
violet and part of blue light. It decreases the effect of
blue sky and brings out the clouds. It is also useful for
taking distant shots on a bright clear day. with this
filter, the sensitivity of films becomes closer to that
of the human eye so that ordinary shots at close
distance will appear very natural with a slightly
enhanced contrast.
O56 (02): Orange filter which absorbs a wider range
of light (from ultraviolet rays to blue-green light) than
Y48, thus producing an intensified contrast. It can
also be used for infrared film.
R60 (R1): Red filter which absorbs violet, blue, green
light and part of yellow light, thus blocking almost all
light except for red and similar colors. As it produces
a strong contrast effect, distant shots turn out sharp
and crisp while the tone of blue sky weakens. This
filter is indispensable for bringing out the effects of
infrared film.
Filters for color films
A4 (81C): On a cloudy or rainy day, pictures taken on
daylight film tend to appear blueish. This amber film
suppresses blue and produces natural color reproduc-
tion. It can also be used for creating warm and mild
effects intentionally under ordinary light.
B4 (82C): Subjects under morning or evening glow
will turn out reddish if they are taken on daylight film.
This blue filter suppresses red and produces natural
color reproduction. In contrast with A4, it can be
used for bringing out cool, blueish effects under
ordinary light.
