PHILADELPHIA — A cell phone photography class at a suburban Philadelphia university focuses on both the quality of the images and the ethical responsibilities that come with taking and publishing them. Cell phone cameras have become so ubiquitous that it’s important for students to realize “the full gravity of what’s at their fingertips and the power they can have,” Immaculata University communications professor Sean Flannery said. Flannery teaches the class with Hunter Martin, a professional photographer who works with students on the mechanics of making the images, including composition, lighting and editing. Flannery deals with such issues as voyeurism, ethics, citizen journalism and the difference between public and private spaces. Cell phone photography courses are not new. New York University has offered a cell phone video class each fall since 2009. Immaculata officials believe theirs is different in addressing the ethical aspects as well.
