The xmp sidecar files are used by Lightroom or Adobe Camera Raw to store edit information. They are of no use to anyone who doesn't have these programs.

When you share images, send them as jpg format images and make sure they are in srgb color space. This is what all of your friends and relatives' computers will expect to receive for viewing.


A little more clarity. When you edit in Lightroom, be it a raw file, JPEG, TIFF, etc. the original file is unchanged. Lightroom saves the edit history and applies it to the original file when you view it in Lightroom. So if you were editing a JPEG and sent that original JPEG to somebody it wouldn’t contain the edits. After editing you need to export the edited image into a new JPEG, (or TIFF), that contains all the edits. The original file never changes.

Note that in Lightroom, if you are editing a jpg, when you go to save it after editing, Lightroom will strongly resist overwriting the original jpg. Instead it wants you to modify the file name so that a new file is produced. However, LR will allow you to save it with the same name but to a different folder. I recommend against this option. There's no problem saving to a different folder, but you really want the file name to be changed to indicate that that file is an edited version and not the original.

That’s not at all how Lightroom works. There is no “save” option. When you’re done editing you export the file. Now maybe you want to change the name just so it’s more descriptive but I would never export to a folder that contains my catalog images. I only export to folders that contain finished work.

I believe .xmp files are not images but what are called sidecars. They carry the recipe for the edits that might have been made in a program like lightroom or photoshop, but have to be associated with the main file of the same name but different suffix to be useful.


Yep. And they can be your savior if your Catalog and it's backups are all corrupted. As long as your file structure is intact all you have to do is create a new catalog and then Import->Add the image files structure at the root folder and you will have a rebuilt catalog with keywords and edits intact.

Correct. I mistyped. I should have written "export".

But while it's advisable to separate the finished work from the original files, it depends on how the user sets up the selections in the export dialog, and they could be set to export to the folder the original is contained in unless the user is keeping track of what they're doing (I'm not sure just what the default setting is there). The dialog can be set up to export to a subfolder of the original folder and the user can specify a name for that folder if it does not already exist. In that case, a re-edit would generate a warning on export that the file exists already and gives you the option to "use unique names".

To share edited images from Lightroom, "Export" the image(s) and share the exported version(s). Otherwise the recipient will get the original, unedited version.

Actually, .xmp files can contain quite a bit of IPTC information (e.g., geolocation, tags, copyright, etc.) regardless of any Lightroom / Photoshop edit info being present or not. As such, they can be useful to people who have never used LR / PS. For example, on Macs original photos can be exported with any IPTC data stored in .xmp sidecar files. The DAM NeoFinder (Mac) will also create .xmp sidecar files for e.g., Affinity Photo .afphoto files.

I have some XMP files that I would like to open but have no clue. Can you advise? And I would like for your comment on this photo as someone wanted to know about settings.


I llike your image, but here are a few compositions things you might want to consider. This is not to say I am a world composition expert, but these ideas are some place to begin.

1. You referenced sunsets, but your photo emphasized the asphalt street. So, shrink the amount of space the street takes up.
2. Any horizontal or vertical line should usually be off-center. In fact lowering the horizon would also help out with #1.
3. Unless you like the telephone pole for composition reasons or clients' desires, I'd suggest trying to not have it in a photo. In my cropped remake of your photo below, I put an X where you might want to stand next time unless that is not your property or there is a ferocious dog at that house. :)
4. Using the 1/3 rule is not a bad way to begin thinking of how to compose a scene, so try putting the main point of the photo at 1/3 of the way from the top or bottom and 1/3 of the way from the left or right.

I have tried to implement these in my crop below, but of course the telephone pole and lines are still there. BTW, as soon as I submit this post, I will delete all copies of this photo from my computer to preserve your rights.

Of course, there may be good reasons to break and ignore all of these ideas, but beginning with them can get one off on the right foot, so to speak.

Keep doing photography. As I said, I like the photo idea. --Richard
