PS exiv2 is an alternative to exiftool if you would like to explore more options. The appended labels are actually tags so if you prefer the _ThumbnailImage embeds, try doing exiftool -b -ThumbnailImage -w _JFR.JPG -ext NEF -r. In my case, there are two resultant files: one with _PreviewImage appended to the filename and the other with _ThumbnailImage. Try doing exiftool -a -b -W %d%f_%t%-c.%s -preview:all dir from above.
Recursively extract JPG image from all Nikon NEF files in the current directory, adding _JFR.JPG for the name of the output JPG files.Įxiftool -a -b -W %d%f_%t%-c.%s -preview:all dirĮxtract all types of preview images (ThumbnailImage, PreviewImage, JpgFromRaw, etc.) from files in directory “dir”, adding the tag name to the output preview image file names.ĭcraw -e does in fact extract an embedded image, just not one that you may want. E.g.:Įxiftool -b -JpgFromRaw -w _JFR.JPG -ext NEF -r. If you like exiftool, there is much more you can do with it.
