I have scanned some old b&w film. When trying to make panorama
from them I get a message telling me that "It is not possible to merge the pictures,
check your selection and try again"
The pictures are overlapping by more than 25% and are Tiff files.
I have no problem merging color files in raw format. Jpg format
haven't been tested.
Is it not possible to merge tiff files?
Export the TIFs as sRGB JPGs and see if those work.
Had a similar issue with Raw files and fixed it by exporting the files as TIFF with the copyright exif data only, stripping all other exif data.
runs like a charm.
You can also strip the exif data for DNG's using Analogexif.
