SHUTTER
The Protune Shutter setting only applies to the Video, Photo, and
LiveBurst modes. This setting determines how long the shutter stays
open. Scroll between the options to see a live preview of each setting,
and then tap the one you want. The default setting is Auto.
For Photo, the options are Auto, 1/125, 1/250, 1/500, 1/1000, and 1/2000
second.
For Video, the options depend on the fps setting, as shown below.
Example 1:

PRO TIP: To reduce the amount of blur in videos and photos when
using the Shutter setting, mount your camera on a tripod or other
stable surface where it won't wobble or shake.

EXPOSURE VALUE COMPENSATION (EV COMP)
Exposure Value Compensation affects the brightness of your photos and
videos. Adjusting this setting can improve image quality when shooting
scenes with sharply contrasting lighting conditions.
Options for this setting range from -2.0 to +2.0. The default setting is 0.
Scroll between the options on the right side of the EV Comp screen
to see a live preview of each setting, and then tap the one you want.
Higher values result in brighter images.
Heads Up: For Video, this setting is available only if Shutter is set to Auto.
You can also adjust the exposure based on a certain area of your scene.
To learn more, see Exposure Control
PRO TIP: EV Comp adjusts brightness within the existing ISO setting. If
brightness has already reached the ISO setting in a low-light environment,
increasing the EV Comp does not have any effect. To continue increasing
the brightness, select a higher ISO value.
