曝光过度凡是曝光过度的胶片,其影像表现在苍白而缺乏反差。产生这类问题的原因比较复杂,其中包括可能是将胶片的感光度控制盘的速度定低了,测光表不准;光圈收缩失灵;快门失灵都可以出现这样的问题。显影过度也会使影像密度增高,但其影像反差也随之提高,可以与之相区别。出现了这样的问题时,要首先检 Overexposed All overexposed film, the image is pale and lack of contrast. The reasons for such problems are more complex, including may be the speed of the film’s speed control panel is set low, inaccurate metering; aperture contraction failure; shutter failure can be such a problem. Overexposure also results in higher image densities, but the image contrast also increases, distinguishing it from it. The emergence of such a problem, we must first seized
