• Adjust the trade-off between noise and motion blur. Go to Settings > Image > Exposure and move the Blur-noise
trade-off slider toward Low noise.
• Set the exposure mode to automatic.
Note
A high max shutter value can result in motion blur.

Handle scenes with strong backlight
Dynamic range is the difference in light levels in an image. In some cases the difference between the darkest and the brightest
areas can be significant. The result is often an image where either the dark or the bright areas are visible. Wide dynamic range
(WDR) makes both dark and bright areas of the image visible.
Image without WDR.
