Bob, EIP works for P-back files, but not the Leica M9, Canon, Nikon, etc. Wayne, I won't say it will happen for sure, but it did happen to me. And, while I'm ranting a bit, Phase One is pushing the various LCC related functions. To do that they have to be saved as presets which gets very stupid after awhile because the list gets really long with a bunch of LCC's that I needed just once.
I've also tried using the color profile editors and saving that as an ICC profile. That gets blown out too each time the app is upgraded. I spent a long time creating those color profiles, so when they went missing after update --- not a happy moment...
I've started creating folders where I store the files used for LCC's and another folder with the original image edited to create a color profile. Then after update I back into that folder and start creating the presets again. Problem is, if I goof up on the naming, then any images that used a LCC X or ICC Y - the file / profile won't be found and C1 gets some heart burn.
I'm hoping these presets / LCC's, etc., live somewhere and I could just copy them back into the new version of C1 via file manager. That work with the LCC's a long time ago (like 3 years ago). But now I think everything is store within C1's "Content" (I use a Mac).
Sorry for going on and on... Hopefully somebody has figured this all out and can share some pearls of wisdom.
