一、序言现在,一般使用的彩色负片和彩色相纸均为高像质高感度,而且加工方便价格便宜。目前还无法用其它产品系统加以取代。彩负和彩纸所具有的高功能,在很大程度上有赖于卤化银微粒具备的高SN 比和高感度性能。它们的主要特点是,对可见光的吸收;各种化学机理协调作用;以及通过显影处理,可以增感10~8倍左右。 First, the preamble Now, the general use of color negatives and color paper are high-definition high sensitivity, and processing convenient and cheap. There is currently no way to replace it with other product systems. The high function of color negative and color paper relies heavily on the high SN ratio and high sensitivity of silver halide grains. Their main feature is the absorption of visible light; the coordination of various chemical mechanisms; and through the development of processing, can be sensitized about 10 to 8 times.
