Photography and graphic technology. Density measurements - Geometric conditions for reflection density Ingestion-build-133579 It provides guidance on assessing1 Scope This part of ISO 5 specifies the geometric conditions for the definition of ISO 5 standard reflection density. It also recommends tolerances on geometric conditions that can be used in the design of instruments. The spectral conditions are specified in ISO 5 3. This part of ISO 5 also specifies the requirements for polarization (if that feature is included) and for backing material, and makes recommendations regarding accuracy and linearity.
