Welcome to Camera Bits Forums
I have found that by ticking the automatically write changes to xmp ,in lightroom Catalogue it does not affect the editing settings in Lightroom when i add additional Metadata. But apparently it i supposed to slow down Lightroom so will have to keep an eye on it.
what would be the correct way then to not lose or modify information:1-In PM select the photos.2-Go to LG and edit those images.3- Finally return to PM to send via FTP, the finished photos?Thanks
