Any help much appreciated.. Beata (Pix4D) January 14, 2019 07:27 Hi Tony! Please open the Processing Options Window and mark the Advanced option which is located in the left-bottom corner of the window. It'll activate the Matching and Calibration tabs. You can read more about calibration options in our article here. Don't hesitate to contact us in terms of any questions. Best!
