Photography. Source document microfilms. Determination of ISO speed and ISO average gradient subscription-only ISO 14064 discusses greenhouse gas1 Scope This International Standard specifies a method for determining the ISO speed and ISO average gradient of black and white camera negative photographic films used for first generation microfilming of source documents at exposure times typically found with tungsten sources. These source documents include any handwritten or printed alphanumeric and line documents such as books, periodicals, business correspondence, and engineering drawings. The
