He was unafraid of exploiting the double-exposure capability of its Compur shutter, as well as soft focus, camera movement and slow shutter speeds. His images are high-contrast, quite unlike the modulated full tonal range of his mentor Cavalli, and are the result of using electronic flash, from overdevelopment of his film and compensatory heavy printing so that nearly-black forms 'float' against a white ground.
He was confident in utilizing the double exposure feature of the Compur shutter, along with soft focus, camera movement, and slow shutter speeds for his photography. His images are high contrast, unlike those of his mentor Cavalli who used a more modulated tonal range. These images were created by using electronic flash, overdeveloped film, and heavy printing to create a near-black form floating against a white ground.
