Caution You can only recall memory data in the same measuring mode. If you
change the measuring mode, previous data is cleared from memory.
6.6 Contrast measurement
To measure the contrast between the main and auxiliary light sources, set the
lumisphere to the DOWN position. Then proceed as follows for shutter speed priority
measurement:
a
Hold your L-408 close to the subject and point the
lumisphere toward the main light source (turn the
auxiliary light source off). Take reading.
ia
Press the Memory button to store the measured
data in memory.
@ Keep holding the L-408 close to the subject and
point the lumisphere to ward the auxiliary light
source (turn the main light source off).
@ Compare the difference in brightness between the
main and auxiliary light sources, and determine the
contrast.
NOTE
*
The contrast can be determined easily

Since the difference is two exposure
increments, the contrast is 4:1.
NOTE
*
To determine the correct exposure, turn both the main and auxiliary light
sources on, point the lumisphere (UP position) toward the camera lens,
and measure the exposure.
