Import a small set of RAW photos into darktable, including difficult highlights, mixed lighting, and high ISO. Apply your normal edits, export the delivery format, and compare color and detail on another display. Reopen the edit history and make a late change without altering the original file.
Test camera and lens support, metadata, and how the catalog moves to another machine. A RAW editor is a good fit when the final images and editable workflow both remain reliable.
