The Schneider 4x4" Classic Soft 1/4 Filter produces a classic Old-Hollywood close-up look, with image quality for current Hollywood needs. Would you like to achieve the same tonality as an old image of Cary Grant or Marlene Dietrich? Hundreds of Micro-Lenslets arrayed within each Schneider Classic Soft filter provide a precisely controlled soft image that is overlaid on a sharp, in-focus image. This combination diffuses the image while maintaining overall sharp focus. Schneider calls this Schneider In-focus Diffusion. The number of Micro-Lenslets per square inch determines the image blending effectiveness of each Classic Soft filter.
