Sekonic L-608 - How to Use a Reflected Luminance (cd;m² or FL) Meter

-28-
5. How to use a reflected luminance (cd/m
2
or FL) meter
1. Make sure that any compensation (see page 29) is canceled.
2. Set the meter to Cd/m
2
or Foot-lambert mode for reflected light with custom setting (see page
33).
3. Set meter to spot reading for reflected light.
Take the measurement by looking through the finder and aligning so the subject that will be
measured is inside the circle.

Reference:
• Setting the meter to EV mode (DIP switch 1) and ISO 100, the measured EV can be
converted to find the brightness level with the below conversion table.
