Using the Flash Meter VI as
a simplified illuminance meter
Attach the Flat Diffuser (ptional accessory), to the meter. In AMBI mode,
hold the Flat Diffuser parallel to the surface you want to measure. Then,
press the incident light measuring button and read the EV value from the
meter. Now, look up the approximate illuminance from the EV-lx
conversion table on the next page.
● Film speed is set to ISO100 (p. 12) and display units are set to EV (p.
69).
● If the instrument has been recalibrated, set it back to the standard
setting of 0 using Alt mode.
★ If you need to measure illuminance precisely, use the MINOLTA
DIGITAL ILLUMINANCE METER T-10, which is designed specifically for
this function.

Using the brightness difference function of the instrument, the lighting ratio
can be read with an accuracy of 0.1 stops.
Alternatively, instead of storing the readings in memory, as explained in
step 6 on page 60, the following method can be used:
6
Press the LATITUDE button. is displayed on the data
panel, and the exposure reading for the main light source is
fixed.
7
Take a reading with the Flat Diffuser facing towards the fill
light source. While holding down the incident light measuring
button, the difference (or lighting ratio) between the fill light
source exposure and main light source exposure, which was
fixed in step 6, is displayed directly on the digital readout.
Read the value.
The lighting ratio of main light source to fill light source can be calculated
from the following table.
Table for determining lighting ratio
Brightness differences Brightness ratio between main
(exposure differences) light source and fill light source
(lighting ratio)
+ 1.0 (1 stop) 2:1
+ 2.0 (2 stops) 4:1
+ 3.0 (3 stops) 8:1
+ 4.0 (4 stops) 16:1
+ 5.0 (5 stops) 32:1
+ 6.0 (6 stops) 64:1
+ 7.0 (7 stops) 128:1
The formula for calculating the lighting ratio is:
Main light: Fill light = 2
Difference
: 1
“Difference” can be either brightness difference in ±EV or difference in
stops between apertures.
Using the Flash Meter VI as
a simplified luminance meter
The Flash Meter VI can also function as a simplified luminance meter. To
determine approximate luminance, press the spot measuring button in
AMBI mode to take a measurement of the desired area of the subject.
Read the resulting EV value in the EV–cd/m
2
conversion table.
● Film speed is set to ISO100 (p. 12) and display units are set to EV (p.
69).
● If the instrument has been recalibrated, set it back to the standard
setting of 0 using Alt mode.
★ To determine accurate luminance, use the LS-100/LS-110 Minolta
Luminance Meter, a dedicated luminance measuring device.
