Neopan 100 Acros achieves the finest granularity for a 100 ISO Black-and-White Film due to Fujifilm's Super Fine-Grain Technology. Neopan 100 ACROS film further develops Fujifilm's existing Sigma Crystal Technology and Super Uniform Fine-Grain Technology by greatly increasing the amount of light captured by the film grains and more effectively utilising the absorbed light. This new film uses Fujifilm's newly developed Super Fine-Grain Technology to overcome the problems of reduced sensitivity that occur with ultra-fine grains, thus creating high resolution and ultra-fine granularity. Fujifilm achieves the world's highest standard in grain quality while attaining excellent intensity reciprocity characteristics. Finer grains bring out the natural beauty of delicate skin tones. This, coupled with its outstanding shadow detail reproduction, broadens the range of photographic expression.
