Setting Spot Meter - JVC GY-HM790CHU Instructions Manual

Setting Spot Meter

The brightness of the object during shooting is displayed.
This function is useful when setting video or stage lighting or
when specifying camera exposure.
A cursor indicating the location and the brightness (%) of that
location are displayed in the images shown on the LCD
monitor and viewfinder screens.
● Zebra patterns display the brightness of output video
signals. (A Page 54)
● This function allows you to check the brightness of input
images from the lens without depending on image
processing such as gamma curve. The dynamic range of
the camera recorder is 300 % and a brightness range of
0 % to 300 % and above is displayed.
Memo :
● Spot meter may not be consistent with the zebra display
range. When [Gamma] in the [Camera Process] menu is
set to ACinemaB or AFilm OutB, the 100IRE output is not
consistent with the 100 % display. (A Page 83)
When an object of more than 300 % luminance is
detected, it is displayed as 300 %.
