Selecting A Measuring Method Suitable For The Light-Receiving Method; Incident Light Measurement - Minolta FLASH METER VI Instruction Manual

Preparations
Selecting a measuring method suitable
for the light-receiving method
Select a measuring method, either incident light measurement or spot
measurement, appropriate to the shooting conditions and nature of the
photograph. The Flash Meter VI can measure exposure in either way. For
incident light measurement, select either the Spherical Diffuser or optional
Flat Diffuser.

1. Incident light measurement

When performing incident light measurements, use the Spherical Diffuser
for three-dimensional subjects such as portraits, and architectural or
landscape photographs. Use the Flat Diffuser when you photograph flat
surfaces such as documents or paintings, or when you want to measure
lighting ratio (See page 58.).
Attaching the Spherical Diffuser
Align the index mark (white circle)
of the Spherical Diffuser with the
index of the receptor head. Secure
the diffuser by turning it in the
direction indicated by the arrow
until it stops.
To take an incident light measurement, position the meter near the
subject and aim the Spherical Diffuser directly at the camera.
● The receptor can rotate through a range of 270 degrees, so that you
can use the meter in an almost any photographic configuration.

Removing the Spherical Diffuser
Rotate the diffuser anticlockwise
until it stops, and pull the diffuser
to detach it.
Never attempt to look directly at the sun through

the viewfinder of the meter. Doing so will
damage your eyesight.
Do not walk around while looking into the
CAUTION
viewfinder. Doing so may result in a fall or other
accident.
2. Spot measurement
To measure a specific area of a photographic image, select the spot
measurement method (with a light-receiving angle of 1 degree).
To take a spot measurement,
• position the meter near the camera,
• look into the viewfinder at the front of the
meter (data panel side),
• locate the measuring index (circle) at the
center of the viewfinder within the desired
measuring point of the subject, and
• press the spot measuring button.
The allowable measuring distance from the
subject is 1.3 m to infinity (∞).
To stabilize your shooting posture and avoid shaking the meter, turn the
receptor head toward the subject and hold the meter by placing your
hand over it as shown above.
Dioptric adjustment
While looking into the viewfinder for a spot measurement,
adjust the dioptric by turning the dioptric adjustment dial
until the measuring index circle can be clearly seen.
