Sekonic MULTIMASTER L-408 - Specialized Metering Applications; Using as an Illuminance Meter; Using as a Luminance Meter

9.2 Using your L-408 as an illuminance meter
@ Set your L-408 to the incident light and ambient light metering mode, and select
@
the IS0 100 and EV display (turn off exposure index correction
).
Set the lumisphere to the DOWN position, hold the L-408 parallel to the subject,
and start metering.
@ Determine the brightness level using the following conversion table or by
calculation.
I? EV-to-Lux conversion table
Display example: EV9 2‘: _
@ Calculation
Brightness level (Lx) = 2.5x2 EV
= 2.5x2 9.4
= 2.5x724
= Approx. 1800 Lx
9.3 Using your L-408 as a luminance meter
(0 Set your L-408 to the reflected light and ambient light metering mode, and select
the IS0 100 and EV display (turn off exposure index correction ).
Q; Measure the object using the viewfinder.

) = 0.125x2 EV
= 0.125x2 4.5
= 0.125x724
= Approx. 90 cd/m
