Measurement
4-2-2. When “E.u” (Exposure under) blinks on the display
If the darkness is beyond the measuring range
of the meter, “E.u” will blink to indicate that
measurements cannot be made. In this case,
if possible, adjust the flash output power
or move closer to the light source and take
another measurement.
5. Measuring contrast of light
This method is useful for setting brightness levels (ratios) of key, line, hair, and
eye lights for cinematography applications or evaluating studio lighting for Photo
applications. It is also useful to check the evenness of illumination across a subject
area or background such as a green screen.
Mount the Lumidisc accessory
(see page 7).
Turn ON just the main light source.
Point the Lumidisc toward the
main light source from the subject
position and take a measurement.
Next turn ON just the secondary
light source. Point the Lumidisc
at the secondary light source and
take a measurement.
Determine the luminance
ratio (contrast ratio) using the
differrence of measuring values
of the main light source and the
secondary light source.
To determine exposure after adjusting lights, turn ON both main light source
and secondary light source, then take a measurement with the Lumisphere
aimed in the direction of camera's lens axis.
