本文探讨了压力对照相性能的影响。一般认为,在多种曝光条件下,胶片受压之后的灰雾总是增大的。由于AgX颗粒中会产生许多新的浅电子陷阱,引起潜影中心的分散,导致感光度的下降。实验证明,在压力作用下,晶体表面感光中心确实向内部移动,但光谱增感染料可以引起压力增感。 This article explores the effect of pressure on photographic performance. It is generally believed that under a variety of exposure conditions, the fog is always increased after the film is pressurized. As AgX particles will produce many new shallow electron trap, causing the dispersion of the latent image center, resulting in decreased sensitivity. Experiments show that under the action of pressure, the crystal surface of the photosensitive center does move to the interior, but spectral sensitizing dye can cause pressure sensation.
