Can't Repair Exif Data
Posted on 2010-08-16
I have a batch of files that were taken with a Japanese mobile phone in 2006 that I'm trying to process. All the metadata I need is in there, but the exposure date/time is wrong. I am trying to fix it, but none of the tools I usually use are working. I have tried a few things with ExifTool, but I can't seem to change the date. For some commands I get this:
Error: [minor] MakerNotes offsets may be incorrect (fix or ignore?) - [path]
0 image files updated
1 files weren't updated due to errors
I have also tried GraphicConverter's time shift function (which I suspect actually uses exiftool), but nothing happens. No errors, but no changes. The only way I have been able to fix it is to open in Photoshop and save a copy, thereby forcing a new metadata header to be created. But that means I have to recompress the data and I don't want to do that. Any ideas how to solve this?
