JC: It is the only circumstance in my practice where the gaze is not direct, because I am not directly engaging with them. I use my cell phone to capture a moment when someone has captured my attention. It’s about seeing and being seen. The engagement is just different than in my big portraits, where they’re all people I know and have asked to participate in the process. [In the subway paintings,] I’m interested in color, composition, and the subtlety of how people carry themselves.
