How to insert EXIF data into a RAW (NEF) image file

THis is not striclty PhotoKit but maybe someone knows?


I want to simply add some keywords to a RAW file (Nikon NEF to be precise) and find it seems that the CGImageDestination cannot write out to anything other than PNG, JPEG, JPEG2000, TIFF, PICT and GIF.


Anyone please have any ideas?

Hi Joanna,



yes ImageIO/PhotoKit can't modify EXIF data in RAW files. This library should be your best option: http://www.exiv2.org


Cheers,


Hendrik
