Abstract: A method is disclosed for quickly and efficiently calibrating the color filtration levels of a photographic enlarger for the characteristics of the printing paper on which prints are to be made, and subsequently adjusting the enlarger for optimize adjustment of the color values for final printing. A test print is made of a standard transparency in the conventional manner. A charge coupled device (CCD) TV camera is then substituted for the printing paper. The output of this camera is connected to a video monitor and to an oscilloscope set to show the amplitude of its output over time. The input of this camera is adjusted to match the color values of the first test print, and the enlarger is adjusted so that the colors in the image showing on the video monitor screen are correct. The transparency to be printed is then substituted for the standard transparency and the enlarger adjusted for correct color filtration levels for the transparency to be printed.
