5. How to use a reflected luminance (cd/m
2
or FL) meter (L-758DR/758D)
1. Exposure/Calibration compensation: see page 36 & 37, Compensation of camera exposure
profile: see page 46.
2. Set the meter to EV mode and ISO 100.
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.
4. The measured EV can be converted to find the brightness level with the conversion table below.
6. Advanced Functions
Reference:
• L-758CINE can read cd/m
2
or FL directly when the custom setting function is used (refer
to page 40).
* EV value → cd/m
