Do I still need to take panel shots if I am using a sunshine sensor?

Yes. An image of the calibrated reflectance panel is still needed both before and after flight to confirm the calibrations of the camera and the sunshine sensor or Downwelling Light Sensor (DLS). When performing the panel capture, ensure that both the panel and the sensor are being exposed to direct light from the sky, without shadowing and without reflections from other objects. In the future, we hope to improve processing such that the panel shots are no longer needed when using the DLS or sunshine sensor.
