    QCamera or QML Camera on Android how to adjust the brightness ? I try to modify manualIsoSensitivity and exposureCompensation , no effect, althought i can implement by MultiEffect with image or videoouput , i think should have a property to changed camera itself ?

      @LZHD If "brightness" means exposure here then setExposureCompensation() should work. Please show how you're using it.
      You should also check whether changing exposure compensation is supported using https://doc.qt.io/qt-6/qcamera.html#supportedFeatures-prop

        @jsulm i try to setExposureCompensation seem not any changed. I try to console supportedFeatures is 32 in hex is 0x20 that means it is only support FocusDistance. Qt's camera also supports too few features on Android compared to Java.

          @LZHD OK, if supportedFeatures says exposure compensation is not supported then it will not work with Qt.
          What Qt version do you use?
