Polaroids occupy a special place in the hearts of many photo enthusiasts who remember a time when "instant photography" meant a one-of-a-kind prints that developed within minutes of clicking the shutter. What was once a crucial tool for photographers to test their shots before shooting on film has now become obsolete in the face of digital photography. Luckily for us, legendary photographer Helmut Newton saved his test Polaroids, allowing a privileged and rare chance to see the tests from a selection of his greatest shoots over a period of decades, including many from the TASCHEN titles SUMO, A Gun for Hire, and Work. Put together by his widow, June Newton, his collection captures the magic of Helmut Newton photo shoots as only Polaroids can.
