Moto Camera Tuner U is a discontinued app from Motorola that allowed users of select Motorola smartphones to manually adjust various camera settings beyond what was available in the default camera app. It offered granular control over parameters like :

*

ISO:

Control over the camera[SQ]s sensitivity to light.
*

Shutter speed:

Control over how long the camera[SQ]s sensor is exposed to light.
*

White balance:

Adjusting the color temperature of the image.
*

Focus:

Manual focus adjustments.
*

Exposure compensation:

Fine-tuning the overall brightness of the image.

Essentially, it provided a more professional-level camera experience than the standard app, enabling users to experiment with different settings and achieve specific creative effects. However,

it[SQ]s no longer available for download or supported by Motorola.

The functionality it provided may have been integrated into newer Motorola camera apps or is simply unavailable on newer phone models.
