50年来,摄影家们一直在寻求一种颗粒小、细部好、感度适中,能快速加工的反转片。最近,富士胶片公司提供了一种名叫Velvia ISO50的新片种,不仅具备上述特性,而且适应于E-6加工。新胶片的主要特点是:采用了双重结构颗粒乳剂,以增强潜影的生成使颗粒超细化。Velvia胶片中还混入了扁平颗粒和立方颗粒乳剂,这样颗粒均匀分布减少了光散射现象,从而改善了清晰度,并减小了颗粒度。Velvia胶片的另一特点是:采用了DIR成色剂技术。在首显中,成色剂根据影像密
For 50 years, photographers have been seeking a small, well-detailed, moderately sensitive, fast-processing reversal film. Recently, Fujifilm provided a new film called Velvia ISO50, which not only has the above characteristics, but also adapts to E-6 processing. The main features of the new film are: The dual structure of the grain emulsion to enhance the generation of latent images to make the particles superfine. Velvia film also incorporates flat particles and cubic grain emulsions, so that even distribution of particles reduces light scattering, resulting in improved clarity and reduced particle size. Another feature of Velvia film is the use of DIR coupler technology. In the first display, the coupler according to the image density
