标准摘要
[中文适用范围]： 该方法的原理是按规定曝光和处理样品，从所得图像中获得密度测量值，以生成感光曲线，从中获取值并用于确定 ISO 速度和 ISO 范围。 该方法适用于主要光谱灵敏度在350 nm至450 nm范围内的囊泡缩微胶片，用于从正片原件产生负片图像，从负片原片产生正片图像。 [外文原描述]： The principle of the method specified is exposing and processing samples as specified, obtaining density measurements from the resultant images to produce a sensitometric curve from which values are taken and used to determine ISO speed and ISO range. The method applies to vesicular microfilms which have their principal spectral sensitivity in the region of 350 nm to 450 nm and are used to produce negative-appearing images from positive originals and positive-appearing images from negative originals.
