Appratus for determination of exposure values for color printing |
| abstract |
Prints of color photographic negatives are obtained by scanning a finite number of unit areas on a negative to determine certain of its criteria for blue, green and red colors. Such criteria are compared with sets of reference criteria which are stored in a memory unit together with empirically determined optimum correction factors for each set of reference criteria. The comparison is made for the purpose of locating or selecting those correction factors which are best suited for adjustment of the exposure control in an automatic printer. The thus obtained information is fed to the exposure control not later than when the freshly scanned negative enters the printing station. |
