Alexey,
thank you, I am very sorry, I think there is a misunderstanding, we have only one subset in photoscan pointing in several folders in windows, we merged the folder in windows, so we get wrong path in photoscan for some images.
Selecting all the camera in photoscan and change the path doesn't not apply the correct path for all the photos, some path remains unchanged that it is not normal I think (selecting the unchanged camera individually and changing the path works but it is very long). Excuse my English, and thank you for your patience, but we still think that it is a problem in photoscan.
Thanks.
Pascal
