Abstract
A method for constructing a transform for a predetermined display or printer, such printer being adapted to form a black and white or color print, on a particular medium, the input to the transform being a digital image file produced by a particular image capture device including providing an input characteristic curve which is a function of the output color code values from the image capture device and relative log exposure of the scene; providing an aim curve which is a function of the visual density of the display or colored print and the image capture relative log exposure wherein the mid region of the aim curve has a range of contrasts between 1.00 and 1.30 to a relative log exposure of 0.6 above scene white and a mid-scale contrast of between 1.0 and 1.7 at a relative log exposure of 1.45 above scene white and the shoulder of the curve ends at the maximum density Dmax) of the particular medium and the toe of the curve ends substantially at the minimum density (Dmin) of the particular display or medium; and providing an output characteristic curve which is a function of the input color code values to the predetermined display or printer and the visual density from a display or print on a particular medium. The method further includes using the aim curve, the input characteristic curve, and the output characteristic curve to produce the transform.
