Trope Publishing Company's new Mobile Edition Series identifies fine art photographers shooting in a new way, using mobile devices as their primary tool to capture images, in a category still defining itself. Among the millions of images posted to social media every day, the work of these photographers stands out for its discipline and mastery. Jess Angell - aka Miss Underground - has been involved with Instagram nearly from its beginning. After posting a few shots of her favorite London Underground stations, she realized those images got much more attention than her usual posts, and @missunderground was born. Jess's work celebrates the Underground's beautiful and varied geometry and architecture, as she hunts and waits to capture these normally crowded spaces empty of people. Fall in love with these subterranean spaces as their hidden angles and details are revealed.
