Summary This standard specifies the description of measuring the degree of sample modulated radiation flux and spectral geometry conditions terminology, symbols, coordinate system, suitable for photography and radiation science. It is primarily required for measurement or photographic material and reflection characteristics of the transmission method to provide a system description. Note: In addition to the language used in official terminology ISO, the international standards gives the German equivalent terms. According to ISO/TC 42 Technical Committee's request already includes them, and should be members of the body of the request in German, FR (DIN) publication. However, as an ISO terms and definitions, can only be considered in the official language of the terms and definitions given.

Foreword

GB/T 12823 "photographic density measurements" is divided into four parts. --- Part 1. Terms, symbols and notations; --- Part 2. Geometric conditions for transmission density; --- Part 3. Spectral conditions; --- Part 4. Geometric conditions for reflection density. This section GB/T 12823 Part 1. This part identical with ISO 5-1. 1984 "photographic density measurements --- --- Part 1. Terms, symbols and notations" (in English). This section is equivalent translation ISO 5-1. 1984. Technical content of ISO 5-1. 1984 is consistent. For ease of use, this section made the following editorial changes. a) "This part of ISO 5" be replaced by "GB/T 12823 in this section"; b) use a decimal point instead of a decimal comma ",". ","; c) Delete ISO 5-1. 1984 Foreword. The ISO 5-1. 1984 Introduction This section is directly translated into the introduction; d) Normative references introductory phrase file to GB/T 1.1-2000 specified key words. This Part replaces GB/T 12823-1991 "Term Symbol photographic density measurement, the coordinate system and functional notation." This section compared with the GB/T 12823-1991, the main changes are as follows. GB/T 11500-2008 photographic density measurements - Part 2. Density perspective geometry (ISO 5-2.2001, IDT) GB/T 11501-2008 photographic density measurements - Part 3.
