Self-defined IQ parameters for demanding customers
YI 4K+ Action Camera comes with multiple high-level settings, such as up to 30 seconds of exposure time, EV compensation settings, ISO, Metering Mode, White Balance and etc. With 9 shooting modes, you can shoot like a professional photographer.
WB (White Balance)
Users can adjust the white balance settings to change the overall color of the video or photo.
White Balance Setting
Recommended Lighting Conditions
Auto (Default)
Automatically adjusts the white balance via environment, without human intervention.
Native
The original color
Tungsten
3000K, tungsten or sunrise / sunset lighting conditions
Daylight
5500K, cool fluorescent, average daylight conditions
Cloudy
6500K, cloudy environmental conditions
ISO (Level of sensitivity)
Change the camera sensitivity to light in low light conditions, in order to enhace the brightness of the videos and photos. In low light conditions, high ISO value will grant a brighter picture, but will also increase the noise level, making it grainy.
ISO for video: Auto (Default), 400, 800, 1600, 3200, 6400
Lock ISO: The ISO will be locked when in manual mode of shutter speed and max ISO, generating a more stable video quality; better for post-editing.
ISO-Max and Iso-Min for Photo
Resulting Photo Quality
Auto (Default,only for ISO-Max)
Automatically adjusts the sensitivity according to the environmental conditions
100
Bright photo in outdoor daylight, minimal image noise
200
Bright photo in indoor lighting, marginal image noise
400
Darker photo in low light, moderate image noise
800
Darker photo in very low light, increased image noise
EV
(Exposure Value compensation)
It influences the brightness of the video or photo. When shooting in a contrasting light environmental conditions, you can adjust this parameter to control the brightness of the video or photo. Value adjustment will increase the brightness of the video or photo based on the default basis.
-2.0, -1.5, -1.0, -0.5, 0(Default), +0.5, +1.0, +1.5, +2.0
