--- Comment #27 from Guenther M. Erhard <guenther-digi...@erhard.mobi> --- Yes, the thumbnail after import from camera is now o.k. - regardless of the option setting. The problem starts when meta data is written to the raw, e.g. adding a tag or correcting time. I've done some tests: - change of time in dk53 with the batch tool on a virgin raw file (with thumbnail o.k.) - after change of time thumbnail get blurry - change of time with exiftool on this file (exiftool -createdate+=00:00:01 FILENAME.ORF) - exiftool throws out a warning: "Invalid time string (2016:10:06T15:14:12) when shifting CreateDate - GME15826_1.ORF" and rewrites the file with the new time - after that thumbnail is o.k. again - doing the time change with exiftool on a virgin raw file gives no warning and the thumbnail is still o.k. Now I tried it with exiv2: exiv2 -v -Q d -a 01:01:00 ad FILENAME.ORF: - changing time on a virgin raw file leaves the thumbnail o.k. - changing time on the dk53 time modified file throws no warning and the thumbnail is still blurry So I guess you are right there is something with libexiv2 as exiftool works correctly. My conclusions: - Exiv2 seems not so picky about errors in metadata and copies/writes them again on file changes - If the file metadata is correct exiv2 does not break the file structure when writing - DK works correct when metadata structure is not broken - Writing metadata with DK (using libexiv2 I assume) into orf raw breaks the structure So I think there is either something wrong in DKs interface to libexiv2 or libexiv2 works different to exiv2.
