| 摘 要： | 本文研究了显影邻界效应。为了便于比较,无论在黑白显影或彩色显影中都使用了对苯二胺型显影剂。在黑白显影中,大面积密度差(H)和浓边密度增量(δ)之间存在着线性关系: δ=αH+b 直线的斜率α可以用作邻界效应强弱的度量。本文研究了显影剂活性、浓度、显影时间和显影液的pH对邻界效应的影响。在彩色显影中银影像和染料影像的邻界效应的关系呈显出复杂的情况。

| Abstract: | The adjacency effect in photographic development was studied. The p-phenylene-diamine type developers were used in both black-and-white and color development for the convenience of comparison. In black-and-white development a linear relationship was found to hold between the density increment on the boarder side (δ) and the large-area density difference (H) for a given film-developer combination:δ = αH + b a can be used as a measure of the magnitude of the adjacency effect. The influences of developer activity, concentration of developing agent, developing time and pH of the developer on the adjacency effect were also studied. In color development a complicated relationship between the adjacency effects of silver and dye images was observed. |
