Bug writing EXIF data

[tlum]

I have recently switch back to SilverFast in my workflow and can no longer update EXIF tags using exiftool. All of my images now have a fatal error in the EXIF data that prevents the tools from working. Images over a certain geometry cause this error, which is 100% of the work I'm doing. There is also a problem with MakerNotes. This is bad but not fatal. Sample file is available here: http://www.tedworld.com/exifTest.tif Excerpt of email with exiftool writer follows. Please fix this bug! SilverFast will need to come out of my workflow as it has brought everything to a complete halt. It does not matter how great most of it is, its useless if all it can write is corrupt files.

Thanks,

Hi Ted,

Thanks for the sample.

The problem is that there is an invalid ExifIFD pointer stored in IFD1 of this image. See the attached verbose dump (-v output). I also tried to open the image in GraphicConverter, and it gives a format error and won't open the image in IFD1.

Dear Ted,

in my current sources I have corrected the ExifIFD pointer in IFD1.
The ExifTool still complains about the "Unrecognized MakerNotes".
Is there a way to tell it to ignore the MakerNotes and edit the rest of the Exif data as requested?

Best regards
Martin

The "MakerNotes" warning is not a fatal error in my experience. -m (-ignoreMinorErrors) should ignore that problem. The IFD1 was fatal however.

In fact, exiftool would be expected to have a problem with MakerNotes since that tag is vendor proprietary. exiftool would not complain if MakerNotes were to be written in EXIF format but there is no constraint that compels you to do that aside from the obvious "compatibility" with other applications.

I think there's a way to ignore the MakerNotes and edit the rest of the data as requested..
