Photography and graphic technology. Density measurements - Geometric conditions for transmittance density Ingestion-build-48068 4 Principle1 Scope This part of ISO 5 specifies the geometric conditions for measuring ISO 5 standard diffuse and f 4,5 and f 1,6 projection transmittance densities. ISO 5 standard diffuse density is primarily applicable to measurements of photographic images to be viewed on a transparency illuminator, or viewing box, to be contact printed, or to be projected with a system employing diffuse illumination. ISO 5 standard projection density is primarily applicable
