Summary:In the digital photography system, the tonal characteristics of the system is evaluated by Camera-through Sensitometry: CTS as the traditional photography. The tonal characteristics of reproduction image on the CRT monitor shot by digital steel camera. DSC was directly measured by colorimetric analysis. The lightness data on the displayed softcopy image of lightness linear single color step charts showed linear relation with the input data level. The slope of those characteristics indicated the qualitative tone characteristics of DSC. The authors also newly propose the introduction of sectional classified tonal charts for the shadow, mid-range and highlight tonal regions.
