X 线胶片的影象质量,除了与摄影因素和暗室处理有关外,还与胶片本身的照相性能关系极大。目前感光材料的生产日臻完善,X 光胶片的使用技术,远落后于胶片的生产技术。只有正确了解胶片特性,才能最大限度地发挥其最佳性能。了解和掌握胶片的各种照相性能,是指导选择摄影条件、保证照片质量的重要问题。为此,我们对上海感绿片、上海感蓝片和天津感蓝片进行了感光测定。通过特性曲线了解胶片的各种性能,用以指导摄影工作,收到了良好效果。现简介如下:
X-ray film image quality, in addition to photography factors and darkroom-related, but also with the film itself has a great relationship to the photographic performance. The current production of photosensitive materials is improving, the use of X-ray film technology, far behind the film production technology. Only with the correct understanding of film characteristics can it maximize its best performance. Understanding and mastering the various photographic properties of films is an important issue that guides the selection of photography conditions and guarantees the quality of photographs. To this end, we have a sensitometric determination of Shanghai Green Sense, Shanghai Sense Blue and Tianjin Sense Blue. Through the characteristic curve to understand the film’s various properties, to guide the photography work, received good results. The brief introduction is as follows:
