XMP files? I never heard of them...I have been editing for many years now, I use Photoshop full edition and have been working with RAW but I don't think I have ever seen the .xmp in a processed image I made or stored. Where does it appear? Is Lightroom that has a separate system that shows .xmp? I have Lightroom with the new CC but it so alien to anything I have ever used it has been useless for me, I don't have hours to relearn and so far do perfectly well with just keeping folders.
When working on a raw file using the camera mfg's software, edits are saved directly into the raw files, just like when working on a JPG.
However, when using software that is NOT from the camera mfg, any edits to a proprietary raw file are saved within a sidecar file, an XMP file.
The XMP file is named the same as the raw file that is being edited, except for the .XMP extension and it is placed in the same folder as the raw file.
As long as these two files remain together then software that can deal with raw & XMP will display the file with all the edits that were done, for example cropping.
Remove the XMP file, or decode the raw in a viewer that does not understand the XMP file and the original raw file is displayed uncropped.
The strength of Lightroom is in it's Asset Management functions - its a database for your images. It will organize and manage the folders where your images reside, but also allow you to search, group, find, organize by pretty much any metadata embedded in your images.
It is also a great parametric editor that compliments Photoshop as a pixel editor.
I moved from Aperture a few years back - it is a catalog based management system, so moving to Lightroom was fairly easy for me, they both use the same basic principles, but Lightroom is much much better in my opinion.
