4-2-2. Measuring with Reflected Light System
Use 5-degree Viewfinder, reflected light
attachment, (sold separately) to make reflected
light readings with the L-478 Series.
This method measures the brightness (luminance)
of the light reflected from the subject. It is useful
for distant objects such as landscapes, when
you cannot go to the position of the subject , or
for metering subjects that generate light (neon
signs, etc), highly reflective surfaces or translucent
subjects (stained glass, etc).
Reflected light measurements are made at the
camera position by aligning the circle in the
viewfinder eyepiece with the subject area to be
measured.
* See operating manual included with 5-Degree
Viewfinder (sold separately).
