You can't directly change your Lightroom name. Lightroom doesn't have a user profile or account system where you can modify your display name.
However, you can achieve a similar effect by:
- Changing your computer's user name: This will change the name associated with your Lightroom catalog files, effectively changing the name displayed in Lightroom.
- Creating a new Lightroom catalog: You can start a new catalog with a different name, essentially creating a new "profile." This allows you to organize your photos separately from previous catalogs.
- Using a different name for your Lightroom catalog file: You can rename the catalog file itself to reflect a different name.
Remember that changing your computer's user name or creating a new catalog will not affect your existing Lightroom presets, plugins, or other settings.
