This British Standard is published under the direction of the Consumer Products and Services Sector Board whose Technical Committee CPW/36 has the responsib

6、ility to: aid enquirers to understand the text; present to the responsible international committee any enquiries on interpretation, or proposals for change, and keep UK interests informed; monitor related international and European developments and promulgate them in the UK.

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Comp

8、liance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, theISO title page, page ii, pages1 and 2, an inside back cover and a back cover. This standard has been updated (se

This will be indicated in the amendment table on theinside front cover.BS ISO6036:1996 ii BSI 11-1998 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodie

10、s). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and n

11、on-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodie

12、s for voting. Publication as an International Standard requires approval by at least 75% of the member bodies casting a vote. International Standard ISO6036 was prepared by Technical Committee ISO/TC36, Cinematography. Annexes A and B of this International Standard are for information only.BSISO 603

13、6:1996 BSI 11-1998 1 1 Scope This International Standard specifies principal density values for colour 16mm and 35mm motion-picture prints and slides intended for television transmission. 2 Normative references The following standards contain provisions which, through reference in this text, constit

14、ute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the

15、 standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 5-2:1991, Photography Density measurements Part2: Geometric conditions for transmission density. ISO 5-3:1995, Photography Density measurements Part3: Spectral conditions. 3 Density

16、requirements 3.1 The method of density measurement and the spectral quality of the densitometer shall conform to ISO5-2 and ISO5-3 respectively for ISO standard diffuse visual density. 3.2 The density corresponding to television white level shall be equivalent to 0,25 to 0,4 neutral density, includi

17、ng base density. This value is not intended to apply to specular highlights and other small areas where details need not be reproduced. NOTE 1For films intended for direct projection, minimum densities depend upon the gray-scale characteristics of the film system used. 3.3 The maximum density of a f

18、ilm print is determined by the scene contrast and the film transfer characteristics. Shadow areas in which pictorial details are not present and in which the reproduction of detail is not essential to the picture may have densities in the range of 2,0 to 2,75, but it shall be recognized that, in suc

19、h areas, both image gradation and colour may be distorted or lost entirely. The density range for optimum colour reproduction is expected to be between 0,4 and 2,0.BSISO 6036:1996 2 BSI 11-1998 Annex A (informative) Additional data Television white level normally corresponds to a fully lit object in

20、 the scene, having a reflectance of about 60% to 70%. This results in the reproduction of fully lit human faces which have reflectances of35% to 15% at film densities 0,2 to 0,5 greater than the density corresponding to television white level.BSISO6036:1996 BSI 11-1998 Annex B (informative) Bibliogr
