彩色印片的关键在于使用何种滤色片和采用多少曝光时间。当然,这里也有一个显影加工的问题。若按规定条件显影,那么滤色片的使用方法和曝光时间则成为问题要点了。使用适当的滤色片,像黑白片那样地进行不同密度级印片,再通过调节滤色片来校正色彩,然后再进行阶段曝光。这种试验反 The key to color printing is which color filter to use and how much exposure time to use. Of course, there is also a problem of development and processing. If the provisions of the conditions of development, then the use of color filters and exposure time has become a major issue. Use the appropriate color filters, like black and white film as different density printing, and then adjust the color filter to adjust the color, and then stage exposure. This test is reversed
