  • Unknown TIFF IFT tag is caused with we rotate the file in Windows Photo Viewer and close the program; the image is then saved by Windows Photo Viewer, modifying the TIFF inappropriately. A private IFT tag was assigned to the TIFF by the Windows software. Still valid and well-formed.
  • Type mismatch for tag 700, expecting 1, saw 7. None of these files are either valid nor well-formed. Edited in Camera Raw. Some of these ARE still camera raw files, given .tif extensions. Those must be repaired by hand. The others can be opened/closed in Irfanview to repair.
