Since the
VP
-1 provides continuously variable control , you may
visually estimate changes in light output when the
Varipower Dial is
set with the
Varip
ower
Index Mark midway between marked position
s.
NOTE:
Th
e minimum Varipower Dial setting
is
marked with a dot (
.)
at
which point
th
e
VP-1
will limit light output to approximately
1/ 6401 lull manual power. A lew t
es
t exposures will quickly
establish the light output
01
your 283 using this minimum dial setting.
Using the Exposure Correction Scale -
Th
e Exposure Correction Scale ® indicates the difference between
exposure
at
full manual power and exposure at a selected dial
setting. This difference is indicated in a number of
lull
I-
stops.
Th
e
minus symbol preceding each exposure correction
serves
as
a
reminder that the exposure is less than that obtained with
lull
power
and that the camera lens must be opened by the indicated
number of I-stops.
