Photographer Nick Briggs uploaded quite a few of his photos from a promotional photoshoot of Claire (Caitriona Balfe) and Jamie (Sam Heughan) from the first season of Outlander. We have seen a few of these photos before, but many of these have never been season before. Nick has the photoshoot labeled as pre-production, so these photos may have been shot before filming began.
Thanks Outlander Italy via Veronica for finding these.
