Keep Gain in MANUAL mode (push GAIN / ISO button until "A" disappears in
viewfinder) - do not ever shoot with auto gain!
Camera switch under gain button has Low, Medium, and High gain modes. Gain
values can be customized in MENU > CAMERA SET > GAIN SET
Shutter Speed
Changing the shutter speed can also change the brightness (slower speed =
brighter... but motion will look blurrier at slower shutter speeds). Press shutter
speed button and use menu dials to dial speed up or down.

Zebra Stripes (highlights areas that are overexposed)
MENU >
DISPLAY SET
The zebra stripes are an exposure control tool that places white diagonal zebra
stripes on the LCD display to mark all areas of the image where brightness has
exceeded a certain IRE threshold. These IRE values can be customized.
Zebra 1 default setting is 70. This is more or less the target brightness value for
Caucasian skin.
100 IRE should be your target maximum brightness. 100 IRE is the Broadcast safe
Max. Video for broadcast that will be color corrected can exceed this range so
long as levels are brought down in post. You can switch your Zebra level to 100 to
make sure nothing is triggered at that setting.
When setting exposure, you can use several Zebra levels to get a more precise
sense of the exposure range in the scene. For example, if you are shooting a
Caucasian face, you should be aiming for around 70 IRE in the skin tones/ face.
Start with your zebra set to 100 IRE to make sure skin tone is well exposed – none
of the facial highlights should be triggering the 100 IRE zebra. Then dial down to
70 IRE to check the highlights – you should now see zebras on the face's hotspots
(tip of the nose, forehead, etc).
