Purpose: Softening of super-critical definition producing striking fluffy halo-effects, especially with back-lighting.
Explanation: The taking lens Of the Rollei gives super-critical definition required for the majority of exposures. If, occasionally, softer definition is desired (e. 9. for portraits and certain dramatic effects) this is obtained by attaching the Rolleisoft Soft Focus Lens in front of the lens.
The Rolleisoft lens consists at a plane parallel glass disc with a few concentric ground-in grooves. While otherwise the lens permits only sharpness or softness through adjustment of the focus, the Rolleisoft lens obtains both simultaneously: Between these grooves the rays of light pass unimpeded to the film and produce a sharp impression, i. e., the basis of the image. At the grooves, however, the light rays are diverted with the result that an additional image of slightly softer definition is superimposed. Both together produce the soft focus effect: The exposure shows fluffy softened contours and sunny halo-lights; distracting fine details recede and the fatal impression of depth definition is improved. By means of the Rolleisoft the Rollei-lens becomes a soft focus lens.
Application: Best results are obtained by using the entire surface of Rolleisoft, i. e., with full aperture. With Rolleisoft 1 (with increased number Of grooves) it is permissible to stop down to f: 5.6. Smaller apertures tend to decrease the soft focus effect.
Rolleisoft 0 is used for weak soft faces effect: primarily for strong contrasts of light and glittering objects, i. e., chiefly for backlighted subjects. Rolleisoft t is used for greater soft focus effect: for soft lighting. — Chief field at application generally: portraiture. Best suited tar: contrasting, highlighted subjects. Rolleisoft increases the plastic, sunny character of backlighted pictures. Speed and focal length remain unchanged. Generous exposures increase the halo-effect. The ground glass screen shows full focused sharpness when using Rolleisoft lenses. The Rolleisoft effect can be judged at any time an the ground glass screen by placing the Rolleisoft in front of the finder lens.
