1. Set the lighttable view to only show images with a rating of exactly 1 star using the _view_ setting on the [top panel](../user-interface/top-panel.md). Since darktable assigns a 1 star rating to newly-imported images by default, this will show all of the images you have just imported. You can use the [collections](../../module-reference/utility-modules/shared/collections.md) module to further refine your selection if needed.

However, in practice newly imported images appear to be unrated.
