Under profile, you can select between 9 different styles, such as normal, day, night or flowing
light mode. Parameters (such as contrast and saturation) will change to match the style. You can
also further modify the configurations for select modes (such as picture, exposure and backlight)
after changing the main style. Flowing light is suitable for situations where there is slight light,
and the panoramic function is unable to effectively detect targets.
◇
After switching to flowing light, the mode in the exposure menu is automatically set to
manual. The shutter time is adaptive, working at a maximum speed of 333 ms.
