上文已讨论了彩色反转片的曲线设计。虽然多数使用者没有曝光仪、密度计,无法测定曲线,但可用灰板代替曝光仪。如果买不到灰板可自制一块,尽管不一定是中性灰,但用几次后,你就能找出冲洗工艺对灰板的响应跟好、坏照片之间的关系。这样,在你的脑海里就有了一条没有画出的曲线。如果能有个密度计把它画出来,当然对你的加工工作就更有指导意义。何为彩色反转加工?概括地说,它是利用首显,也即黑白显影将已曝光部分显成银质负像,使该部位在彩显时不产生染料;然
The curve design of the color reversal film has been discussed above. Although most users do not have exposure meters, densitometers, can not measure the curve, but the gray plate instead of the exposure meter. If you can not buy a gray board can be made of a piece, though not necessarily neutral gray, but with a few times, you can find the rinse process on the gray board with the good and bad, the relationship between the photos. In this way, there is an un-drawn curve in your mind. If you can have a density meter to draw it, of course, your work is more guiding significance. What is color reversal processing? In a nutshell, it is the use of the first significant, that is, the exposed part of the black-and-white display silver negative, so that the site does not produce color in the color dye;
