Measuring fill-in and ambient continuous light
The Flash Meter III can be used to deter-
mine exposure for pictures in which shadows
from daylight or other bright continuous-light
sources are being filled in with flash, since it
can measure both th e fill-in light and the
ambient surrounding light . To do so :
1.
With serviceable batteries properly installed
(p. 12), and arrangement made for incident
or reflected measurement (p. 19), set the
film speed for the film in use and the
display-mode se l ector to "FNo ." .
2.
Set measuring time (p . 19) corresponding to
camera shutter speed to be used from 1
through 1/250 sec. Remember that this
must be within the synchronizing range of
the camera and long enough to cover th e
total flash duration with X delay.
3. Set the measuring-mod e selector to "AMBI"
and measure only the continuous light
without the flash. Then determine and set
the applicable speed-aperture combination
to be used.
4. Set
the mode selector to "COR D" position
for sync.-cord readings with electronic or
M-bulb flash or "NON.C" for cordless elec-
tronic-flash readings.
5.
If applicable, attach desired sync. cord;
flash- unit cords as indicated on p. 39, Sync.
Cord II as on p. 40.
6. Then adjust the flash-to-subject distance so
that a second reading taken with flash of the
flash- lit fill-in area calls for the same expo-
sure as in 4 above. Balance between main-
lighted and filled-in areas can be adjusted to
personal taste and the effect desired by
varying conditions to change the second
reading: A flash
fill-i n readout numerically
smaller (e.g., f / 5.6) than the one for cont i-
nuous light (e.g., f / 8), at which the camera
should be set, will produce less fill-in; a
numerically larger one, more fill-in .
7.
Make the actual exposure with the sync.
cord properly connected with the camera
for X-sync. and the camera shutter and lens
set
for the ambient light as determined in 4
above.
