Description

"Nikon Lens Data" present in the original Raw file disappear in Exif data of jpeg pictures exported by darktable :

exiftool ./DSC_0094.NEF :
- ...
- Lens ID Number
- Lens F Stops
- Min Focal Length
- Max Focal Length
- Max Aperture At Min Focal
- Max Aperture At Max Focal
- MCU Version
- ...

(this causes a crash of the plugin "JpegReader.class.php" in my "Piwigo" galery)

History

#1 Updated by Tobias Ellinghaus 5 months ago

Please upload a raw with the tag present and an exported JPEG that lacks it.

#2 Updated by Bernard CEURSTEMONT 5 months ago

Here is the original (DSC_0016.NEF) and the exported Jpeg (DSC_0016-DT.jpg)

#3 Updated by Tobias Ellinghaus 5 months ago

All of the entries you mention are present in the JPEG you uploaded. exiftool seems to be unable to see them though. Maybe ask the exiftool developers why that is the case, I don't know that tool and can't comment on it.
