Case in point: AMCtv.com's all-new Breaking Bad Black & White Photo Gallery for Season 4. Shot by Breaking Bad's Unit Photographer Ursula Coyote, these striking images include such memorable moments as Walt (Bryan Cranston) buying his revolver, Jesse (Aaron Paul) and Mike (Jonathan Banks)'s road trip, and the tense showdown in Mexico.
