Darin got most of his training informally by assisting for photographers in Italy and working at Shades/Juan Gil Srl., a B&W laboratory in Milan, developing film and assisting the master printer, Maddalena Mori, for clients including various Magnum and Contrasto photographers, as well as fashion, commercial and art photographers.  Seeing the contact sheets and how they worked a scene or photograph helped him considerably in understanding how the decisive moment was really achieved.
