I use Lightroom and so do the photographers I second for.
Sometimes I'll do little things like colour or exposure correct, crop and maybe some creative edits before I pass my images along to the primary photographer for their edit.
I usually export the RAW file along with the XMP (choosing Original) to give them but I just played with an export and when I imported the file onto my other computer the changes I made weren't there. Is there a setting I missed?
Is there another way to do this and give the primary both my edit and the RAW file?
