FUJICHROME Velvia 50 Professional [RVP 50] is a professional daylight color reversal film with an ISO speed rating of 50. Nearly identical in performance to FUJICHROME Velvia for Professionals [RVP], this film was made possible through the development of new production technologies and substitutes for raw materials vital for the manufacture of the current Velvia but now hard to procure. In addition to the world’s highest level of image color saturation and vibrancy, this film combines superb granularity with resolving power. The result is well-modulated, vivid color reproduction and high picture quality, as required in such wide-ranging subjects as nature photography, fashion, products, interiors and artwork. It is especially suited to subjects that demand precision in reproduction and emphasis in colors
