I am using Lightroom 6.14. How do I export a raw image to edit, then after I edit the image, save it with the edits, while keeping the origianl raw file intact?

In Lightroom, "edits" are stored in the database. The raw file stays 100% untouched.

The edits are kind of instructions on what to do when the picture is exported. Pictures are normally exported as JPEGs or TIFF. There is no possibility to create a new raw file, with the exception of exporting as a DNG which is Adobe's open raw file format.

So the basic workflow in Lightroom is:

• import the raw files:

The files are imported from the camera or a storage card and copied to the harddisk at a specified location. You can also import from the harddisk for existing photos.

• Edit:

Modify the exposure, correct lenses, crop, add a location etc. The edits are stored in the catalog file. The raw file is not modified.

• Export

Export as JPEG, TIFF. Your edits are backed to the file. That file can be forwarded to your customer/family/friends.

Your raw allows for different independent edits. As it is nondestructive, you can always return to a starting point.
