When using camera LB/CC lters based on the recommended compensation
displayed in the meter (C-800), please note that camera lens lters block or absorb
light to produce their effect and thus the amount of light passing through them for
exposure will be reduced.
If your camera does not have a through the lens exposure system and you are using
a handheld exposure meter to determine camera settings, consult the table below to
nd how much to increase the exposure to compensate for the light absorbed by the
lens lter.
When you use a lighting lter, exposure compensation is not necessary, because
the intensity of the light is already decreased.
