Example
≫
②
Select the histogram zone (A~D) of the peak position of Tv 4000 from the below.
* In the case of above, the histogram zone is B.
③
Obtain the shutter speed (ms) referring the conversion table.
* In the case of above, difference of peak position is
+1.0mm
and histogram zone is
B
. Therefore,
the shutter speed is
[0.263ms].
