摘要:
The invention relates to a method to establish a sensitometry curve for a photographic medium, including the following steps: the formation on the medium of at least one sensitometry control by exposing many ranges of the medium with various exposure energies; the capture of the optical density values of the sensitometry control in each range; the formation from the captured values of sensitometry curve sections; and the energy offset of the curve section to obtain a partial overlap of sections corresponding to neighboring exposure energies.
摘要(中):
通过使用空间调制曲线调制的能量曝光范围,在胶片(10)的每个范围(21-24)上形成感光度控制(12)。 基于对照的光密度值,在相同的轮廓值的区域中形成感光度曲线部分。 能量偏移被施加到曲线部分,以获得与相邻曝光能量重叠的部分部分。
