一浴显影定影加工法,是在显影液中预先加入适量的硫代硫酸盐,在同一加工液中进行显影、定影操作的简单冲洗方法。通常,彩色底片和相纸的加工都采用最简单的显影、漂定两浴法。彩色感光材料的显影和漂白定影在同一浴中进行是不可能的,所以在彩色相纸的一浴显、定加工中,仍有漂白定影工序。因此,加工工序并未减少。进行一浴显、定加工时,因对显影终了时间、加工温度以及搅拌方法等要求不太严格,故便于操作。不过这种方法得到的画面影像的鲜亮度、色纯度低。所以,只要对画质要求不十分苛刻,该方法还是可用的。
One-bath developing fixing method is a simple rinsing method of pre-adding an appropriate amount of thiosulfate in a developing solution and performing developing and fixing operations in the same processing solution. Normally, color negatives and photographic paper are processed in the easiest way, using the two-bath method. It is impossible to develop and bleach the color sensitive material in the same bath. Therefore, there is still a bleaching and fixing process in the one-bath display of color photographic paper. Therefore, the processing operation has not been reduced. A bath was set, will be processing, due to the development of the end of time, processing temperature and mixing methods are less stringent requirements, it is easy to operate. However, this method of image brightness and low color purity. So, as long as the quality requirements are not very harsh, the method is still available.
