Hi Phil,
using exiftool -validate -error -warning -a I'm getting a warning on some makernote tags on image files from Panasonic cameras.
Warning : [minor] Undefined value for MakerNotes:InternalNDFilter
Warning : [minor] Undefined value for MakerNotes:ClearRetouchValue
Both tags contain a rational64u value of 0/0. Excerpt from exiftool -v3 on this file:
| | | 110) InternalNDFilter = undef (0/0)
| | | - Tag 0x009d (8 bytes, rational64u[1]):
| | | 115a: 00 00 00 00 00 00 00 00 [........]
<snip>
| | | 116) ClearRetouchValue = undef (0/0)
| | | - Tag 0x00a3 (8 bytes, rational64u[1]):
| | | 116a: 00 00 00 00 00 00 00 00 [........]
So the question is: is the warning real and 0/0 is not allowed or is the warning a wrong positive one?
TIA
All makernote errors are minor because the manufacturer is free to do whatever they want. However, ExifTool will warn if there is anything that deviates from the EXIF/TIFF specification if the maker notes are EXIF/TIFF format.
