The color of developed silver chloride papers can vary widely from warm black to blue black if some additions are included in the emulsions or in developers, but there are some difficulties in the measurement of spectral density of the silver deposit on a paper exact enough to specify the color of a print. This is the reason why we used liquid emulsions instead of coated papers, we can easily determine the spectrophotometric density of the developed image by measuring the transmittance of the developed and fixed emulsions in liquid state. As the author pointed out earlier using chloride paper(1), the color of developed prints shifts from original neutralor slightly brownishblack tone to blue-black (curves a, b and c in Fig. 1) or to warmer brown-black (curve d) with increasing amounts of addition agent in developer or in emulsion, and it is a general tendency with blue-black toners that after passing the optimum concentration the color of the images turns to violet or again to brownblack and the developer loses its developing activity sometimes in the course of color change (as indicated with mark x).

As a result of testing of this chart, it was found that this chart gave a very large contrast, being as large as 0.9 compared to the value of about 0.5 for conventional test chart of evaporation-type. It was also confirmed that the incident angle characteristic for an oblique incident radiation of this new test chart was superior to that of the conventional evaporation-type test chart. Further, using this newly-made test chart, the image quality for several kinds of the X-ray films was evaluated. From the results obtained we were able to find quantitatively how the MTF, that is, an evaluating measure of sharpness would be affected when the thickness of film base, the 7-value of film, the velocity of developing treatment, the granularity, etc., were changed.","PeriodicalId":187531,"journal":{"name":"Bulletin of The Society of Scientific Photography of Japan","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128833322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
