# Calibration Images

The 6X can capture calibration imagery using the reflectance panel. This calibration imagery is used to  help correct for changing lighting conditions that may occur during the flight. 

During the calibration image collection process 12 images will be captured where each image has varying exposure/ISO values. 

{% hint style="info" %}
Reflectance panel images should be captured immediately before and/or after drone survey data collection.
