Abstract: A method of predictably producing accurate photoprocessing and graphic arts control tools, to be used for adjusting the parameters of photographic devices, in which a computer-originated image is digitally recorded onto a first recording medium by a digital output recording device, is illuminated and is photographed onto a second recording medium to yield second-generation camera-original control tool photographs on the second recording medium. One or more of the tone, color or frequency response characteristics of the digitally-generated image on the first recording medium are selectively adjusted, using a digital data transform, so that the second-generation control tool photographs on the second recording medium have the tone, color and frequency response characteristics defined as "aim" for that second medium.

Abstract: A method of predictably producing accurate photoprocessing reference image tool photographs to be used for adjusting the parameters of photographic devices, in which a first-generation camera-original image of a scene containing preselected background and subject content is photographed onto a first photographic recording medium. A second first-generation camera-original image of charts containing photoprocessing parameter control information is photographed under the same conditions as the first exposure, onto a second photographic recording medium. The first image is photodigitized into a first digitized image which is stored in a primary digital image data metric in a digital image data base. One or more parameters of the first digitized image are selectively adjusted. Photoprocessing control element(s) (e.g.
