I've tried searching the forum, but couldn't see anything.
Having finally started the mammoth task of keywording my entire library, I realise that I need to know which option to choose from those shown in the attached image for latest version of Lightroom 5. I want to preserve my existing image adjustments as well as incorporate all the metadata I've just written using Photo Mechanic.
I've worked out how to do this successfully and synch new metadata when working in Capture One Pro V8, but recall when I tried in the past with LR, I chose an option that updated the metadata, but effectively wiped all my previous image adjustments. I don't want to do this again for several thousand photos!
So my questions are
1. Which of these options do I choose?
2. Do I need to change anything in LR preferences? If so, then what?
Many thanks
