Exposure Control Code Samplesļ
- Import the interface. This line is automatically added by OnBot Java when the interface is used (coded). 
- import org.firstinspires.ftc.robotcore.external.hardware.camera.controls.ExposureControl;
- Declare the ExposureControl object, before - runOpMode().
- ExposureControl myExposureControl;
- Assign the Vuforia/TFOD video stream control to your control object, in - runOpMode().
- myExposureControl = vuforia.getCamera().getControl(ExposureControl.class);
- Set the mode to Manual, for direct control. 
- myExposureControl.setMode(ExposureControl.Mode.Manual);
- Set the exposure duration, in this case to 30 milliseconds. 
- myExposureControl.setExposure(30, TimeUnit.MILLISECONDS);
See far below for these and other exposure controls illustrated in Sample OpModes.
