ASA Committee Proposes Method for Determining Speed of Film
The American Standards Association is now publishing a proposed method for determining photographic speed of roll film, film packs, and miniature camera films. The method was drawn up by the committee on photographic standardization (Z38), whose project was discussed in a previous issue.1 The method is being published for trial and criticism for a period of approximately one year, at the end of which time it will be considered for adoption as an American Standard.2 If it is finally approved as an American Standard, it is expected that it may be used as a basis for recommended exposures for picture-taking and for assigning speed numbers to films.
