I have had the same issue with no radiometric data in the images. I have usually taken rgb photos knowing the thermal would be shot at the same time. Today I selected IR on the controller display before taking the picture. I pointed the camera into a bucket of ice in my hotel room and what do you know, success. I am going to try that in the field tomorrow. I am also going to try a map. I never have trouble with my
Evo II 640T V3 providing radiometric data in exif's. I am sure this will get ironed out. This attached image is from my Max 4T taken today.
