Warning: IFD 0 ImageDescription has odd data offset
« on: March 18, 2024, 02:02:14 PM »
My Leica SL3 produces DNG files natively.  I have run the dng_validate program from the current Adobe DNG SDK on the result of copying the raw dngs across to my laptop and I get the following:

Code: [Select]
./dng_validate  ~/Pictures/2024/2024-03-17\ Edinburgh/20240317-154230_L1000583.DNG
Validating "/Users/jrp/Pictures/2024/2024-03-17 Edinburgh/20240317-154230_L1000583.DNG"...
*** Warning: IFD 0 ImageDescription has odd data offset (79968567) ***
Raw image read time: 0.335 sec
Linearization time: 0.175 sec
Interpolate time: 0.374 sec
Validation complete

Doesn't seem to cause any harm, so far as I can see, but is there a buglet in the way that the Description of the Image is inserted into the file?

There should not be any problems with the offset to a string being at an odd file offset.
