METHOD FOR FORMING NEGATIVE OF MANY OLD AND LARGE-SIZED BLACK AND WHITE PHOTOGRAPHIC DRY PLATE AND FILM BY MAKING NEGATIVE USING NEGATIVE FILM OF 35 MM SIZE AND INTEGRALLY SORTING OUT THE SAME

摘要

PROBLEM TO BE SOLVED: To make it possible to form precise 35 mm negative manuscripts of simple sorting out by photographing black and white negative photograph dry plates and black and white negative films of various sizes with a 35 mm film for copying and subjecting these films to soft contrast and reversal development. ;SOLUTION: The reversal development is executed in order to form the negatives by photographing the negatives using the negatives. The old black and white negative photographs of various sizes with which the sorting out is extremely difficult are reformed to the 35 mm negatives by using the 35 mm film for copying which is extremely high in contrast but has excellent resolving power. The photographed 35 mm film for copying is subjected to the soft contrast and reversal development as it is and the desired negative is formed by one time of development. If the film of 35 mm is formed by this method, the printing at a service size is possible as well and the formation of a print album and negative album is easy. A digital album may be easily formed as well by using a small scanner for home use.;COPYRIGHT: (C)2000,JPO
