I have two computers, iMac and MBA (Lion).
I treat my NEF only with iMac where I keep NEF+JPG.
I transfer JPG ans XMP (not NEF) on MBA with automatic bidirectional synchronisation (ChronoSync)
Sometimes I add keywords on MBA, for example in picture1.jpg.
After transfer on iMac IPTC of picture1.jpg are fine, not picture1.nef.
I need transfer IPTC from picture1.jpg to picture1.nef on iMac.
So if I do a new work on my nef, IPTC will be fine on new jpg. Actually, I lost y changes.
I know it is possible with info table, but not easy for a big lot.
Is there another possibilty ?
I hoped success with XMP but I have many troubles with preferences-IPTC/XMP.
I find :
When writing IPYT/XMP
For jpeg…
Add embedded… (XMP will aways be written)
I never obtain written XMP !
Thanks for your help.
