Basic Operation
Special Functions
Here we explain how to use the special functions of the MINOLTA AUTO
METER VF.
Memory function
Using the memory button, you can store up to two measurement values in
the meter.
The stored measurement values are displayed on the analog scale by
pointers. As an example, you can use the meter's memory function to
visually confirm the lighting ratio on the analog scale. This is a very handy
feature for tuning lighting conditions. (See page 54.)
1
Press the memory button
after taking a reading.
● The data panel turns off for a
moment as the measurement
value is stored in memory. One
pointer appears at the right of
the analog scale to indicate that
one value is stored in memory.
2
Take a second reading.
● The measurement value is
displayed on the digital readout.
Now, the analog scale shows
both the current reading, as
displayed on the digital readout,
as well as the measurement
value stored in memory in step
1.
●● Using the up/down key to change the shutter speed to 1/40, we can see
how this change will affect the mix of ambient and flash light.
The aperture has changed to F2.8
9
(almost F4.0) and now, only one
quadrant is lit up. This indicates that
the proportion of flash light is now only
25% (ambient:flash ratio = 3:1).
A photograph taken under these conditions will be influenced more strongly
by the tungsten light (orange) and less strongly by the flash light (white).
On the other hand, increasing the shutter speed (within the range of sync)
will have the opposite effect-photos will be more strongly influenced by
flash light (white) than ambient light.
This simulation is based on controlling the ambient light by varying the
shutter speed. The proportions of ambient light and flash light can also be
adjusted by changing the intensity of the flash light.
The intensity of flash light can be controlled either by varying the distance
between the subject and the flash, or by changing the power (light output)
of the flash.
When you are controlling flash light intensity, you must take a new reading
each time one of these two factors is changed.
