White House press photographer Dennis Brack discusses his long career photographing presidents. Having created a museum’s worth of images for the Black Star agency, Brack has now written the book on his craft, “Presidential Picture Stories: Behind the Cameras at the White House.” Brack demonstrates how photographers have covered presidents since the days of Abraham Lincoln. Presidents can stay only eight years but veteran photojournalists like Dennis Brack have spent decades documenting First Family life and fresh history in the White House “fishbowl.” Dennis Brack is a former president of the White House News Photographers Association who averaged a picture per week in Time Magazine for 23 years. He’ll discuss the joys and ordeals of such high-profile, high-pressure work. Recorded at the Arlington Public Library on Nov. 24 2014.
