Author's new simplified method for the sensitometry and grading of photographic papers which was reported recently at the 1965 SPSE Conference (May 17-21, Cleveland, Ohio U.S.A.), is applied for many kinds of domestic papers. Relations to the existing JIS and ASA methods or the formerly proposed DIN method and merits over these methods are discussed and some of the results are summarized in many graphs using these data.
