Content DescriptionISO 5-2:2009 specifies the geometric conditions for measuring ISO 5 standard diffuse and ƒ/4,5 and ƒ/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 to measurements of photographic images to be projected with systems employing optical condensers. Although primarily intended for the measurement of photographic images, the densitometric methods specified in ISO 5-2:2009 are often applied to optical filters and other transparent materials. About ISOISO, the International Organization for Standardization, brings global experts together to agree on the best way of doing things – for anything from making a product to managing a process. As one of the oldest non-governmental international organizations, ISO has enabled trade and cooperation between people and companies all over the world since 1946. The International Standards published by ISO serve to make lives easier, safer and better. |
