Only a handful of photos have been released for Outlander season three, and not all were high-quality images. Below are the photos released thus far in ultra high-quality from Starz, both from the season three episodes and one behind the scenes photo. A couple of released photos are missing from this post.
Characters that can be seen below are Jamie (Sam Heughan), Claire (Caitriona Balfe), Frank (Tobias Menzies), and Black Jack Randall (Tobias Menzies).
