Iliah, Robin, Andrew, Thanks for the responses. They were all helpful. Iliah, I did download RPP and played around with it. I'll need to dig in a bit more before I can really make sense of it. I downloaded the other program too, but my brain turns to fluff when working in Terminal mode. Andrew, I was under the impression (perhaps incorrectly) that LightRoom always updated metadata *automatically* after every change and wrote that to the DNG file. On my system (at least when not sharing files with others) that's how it seems to work. I am hoping your suggestion will help, because I am fairly certain the other guy is NOT doing a "forced save" (Cmd-S) before sending me his DNG files. I'm not on my end either. So, we will give that a trial and see if it solves the problem. I'll let everyone know what I find out. I'll bet Cmd-S does the trick! Thanks again, Lou
