Basic Operation
When making flash light readings, the MINOLTA AUTO METER VF is able
to calculate the proportion of ambient light and flash light in the total
illumination.
The proportion of ambient light and flash light can be checked on the
quadrant proportion indicator of the display.
How to read the flash/ambient light ratio
Whenever you take a flash light reading, the quadrant proportion indicator
is displayed on the LCD data panel. After a reading, you can also do a
simulation to see how changes to the shutter speed affect the proportions
of ambient light and flash light.
The quadrant proportion indicator shows the proportion of flash light in the
total exposure reading as one of five levels (0.1-25%, 26-50%, 51-75%, 76-
100%).
Example of reading, display and simulation
Assume that a tungsten lamp is used as the ambient light source.
●● Reading of F4.0
2 at a shutter speed of 1/80 sec.
Two quadrants are lit up on the
display, indicating that the proportion
of flash light is approx. 50%
(ambient:flash ratio = 1:1).
A photograph taken under these conditions will not be strongly influenced
by either the tungsten light (orange) or the flash light (white).
Display example
The f-number corresponding to the
shutter speed set in step 3 is
displayed on the digital readout as
well as on the analog scale.
Ex.: The display shows an f-
number reading of F8.0+0.9-
stops
If the exposure reading is outside
the display range of the meter, the
f-number is not displayed. Instead,
FNo. and (over) or (under)
will blink to indicate the reading is
out of range. The or indicator
on the analog scale will also blink.
If the reading is outside the
measurement range of this meter,
E (error) will be displayed on the
digital readout, and (over) or
(under), and or on the
analog scale, will blink to indicate
that the measurement is out of
range.
