Abstract: The brightness and density distribution of an object can be digitally measured photographically by exposing a light-sensitive photographic material at a dot screen or the like and to the object to be measured, and photographically processing the exposed light-sensitive material to produce equidensity images in which different densities of the object are differently represented.

Abstract translation: 物体的亮度和密度分布可以通过在点画面等曝光感光照相材料和被测定物体而进行数字测量，并照相处理曝光的感光材料以产生等距图像 对象的不同密度被不同地表示。

Abstract: A process for the production of positive photographic images comprising the steps of imagewise exposing a light-sensitive silver salt emulsion layer, photographically developing to form a negative silver image in the exposed areas, treating the exposed and developed layer with a peroxide compound, the peroxide compound is left to act on the layer until it has been decomposed at the negative silver image, and forming a positive image by decomposition of the undercomposed peroxide compound in the unexposed areas of the layer.

Abstract: IN A PROCESS FOR THE PRODUCTION OF PHOTOGRAPHIC IMAGES BY IMAGEWISE EXPOSURE OF LIGHT-SENSITIVE LAYERS TO IMAGEWISE PRODUCE NUCLEI THAT CATALYTICALLY DECOMPOSE PEROXY COMPOUNDS, WHEREIN THE EXPOSED LAYER IS TREATED WITH A PEROXY COMPOUND AND WITH REACTION COMPONENTS FOR A DYE-FORMING OXIDATION REACTION THAT PRODUCES THE PHOTOGRAPHIC IMAGE, THE IMPROVEMENT ACCORDING TO WHICH THE TREATMENT IS ALSO WITH AN ORGANIC COMPOUND HAVING AT LEAST ONE ALIPHATIC HYDROXYL GROUP AND/OR AN ALIPHATIC OR AROMATIC KETONE, TO INTENSIFY THE DYE IMAGE.
