| Self-defined IQ parameters for demanding customers |
| YI 4K Action Camera has multiple high-level settings such as shutter at an exposure time of 30 seconds; Exposure Value compensation setting (EV), Setting of level of sensitivity (ISO); Metering Mode; White Balance (WB); etc. Together with the choice of 9 shooting modes, you can make impressive work 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 photosensitivity in low light environmental conditions to enhance the brightness for the video or photo. In low light environmental conditions, the higher the ISO value, the brightness the captured video or photo,the greater the signal noise, grainy strong, and vice-versa. |
| Others |
| ISO for Video |
Resulting Video Quality |
| Auto (Default) |
Automatically adjusts the sensitivity according to the environmental conditions |
| 400 |
Darker video in low light, minimum image noise |
| 1600 |
Moderately bright video in low light, moderate image noise |
| 6400 |
Brighter video in low light, highest image noise |
| ISO for Photo |
Resulting Photo Quality |
| Auto (Default) |
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 |
