Non-bias architectural image archive using High Dynamic Range approach

摘要

The paper examines the imagery information and the qualitative characteristic of archiving non-bias architectural image using High Dynamic Range (HDR) imaging approach. Photography imaging became possible in the period of 19 century, it was a combination of several different scientific discoveries. Architectural photo imaging began with monochrome recording limitation, and the dynamic range recorded was inadequate even with analog color film. Often it was arguable if the photography image would provide reliable imagery information, either for aesthetic visualization purpose or to record accurate imagery information. The paper aims to analyze the limitations and issues that affect visual accuracy of HDR imaging digital workflow, including the environmental technical obstacles. Due to the situations of very contrast lighting condition, the extended dynamic range may be needed for archiving the real-world scene of architectural subject. The paper also explores the possibility of HDR imaging as an improved approach for non-bias architectural imaging archive.
