A new episode of Research Rabbit Hole, our Facebook Live show, premiered Monday evening, April 5, at 9 p.m. ET.

Season 1, Episode 7, provides answers to a deceptively simple question: Ever wondered why and how Americans of the 1860s posed for portraits? In this episode, we review instructions by traveling photographer B. Bradley to his patrons to help them make the most of their visit, and guidelines suggested by master daguerreian pioneer Marcus Aurelius Root in his 1864 photographer’s handbook, The Camera, and The Pencil.

The full season is available on YouTube.

New episodes of Research Rabbit Hole will be released every two weeks on our Facebook page. The host, Ronald S. Coddington, is Editor and Publisher of Military Images.
