Abstract

In this paper creation of the photographs with a wide dynamic range (HDR photographs) is analysed through all the stages of digital photographic system. As a major constraint in creating HDR photographs the realization phase stands out, particularly the phase of the digital print of photographs. DOD ink jet printing is one of the dominant techniques for printing digital photographs, especially for large-sized photographs for galleries. In the experimental part of the paper the impact of increased number of inks for DOD bubble jet printing on the surface with the appropriate receptor layer on the dynamic range of the print is examined. Tests in CMYK and Hi-Fi printing based on the defining of maximum densities, optical coverage, transmission curves and chromaticity diagrams were conducted. The results suggest an increase in dynamic range of the prints by increased number of printing inks, but also the fact that the dynamic range achieved in that way is significantly smaller than the potential dynamic range of photographed scene and human vision.
