Guidelines for better measurement methods in high contrast scenes
Focus on metrological aspects rather than artistic HDR photography

Abstract

This Good Practice Guide (GPG) describes the key aspects in high dynamic range (HDR) imaging forthe assessment of glare in scenes using dedicated systems capable of documenting scenespresenting high contrast of luminance. The guide has been developed during the project EPM21NRM01 HiDyn using the experience gathered after evaluating lab and field intercomparisoncampaigns. It describes the typical workflow for ILMD settings to be considered, acquisition of theimage sequence, HDR merging, and analysis of the glare scenes.This GPG aims to help the relevant stakeholder to better understand the challenges of HDR luminanceimaging and to improve their measurement methods.This GPG refers only to the metrological task of luminance measurement in high contrast scenes anddoes not include any discussion and methods for the photography of artistic implementation of HDRalgorithms.
