The difference is that a "short" toe film will yield transfer from linear to full black very shortly. By that I mean that it is the same as film over exposed where the shadow detail is on the linear portion of the curve. In colour, there is no real difference. However, in B&W, Placement of the shadow on the toe yields some detail in the shadow areas before the print goes fully black. In B&W, you must adjust your exposure, development, and printing practices to yield satisfactory detail in the shadow areas. Older emulsions like Tri X and Plus X have a long toe compared to the later......that is why they are still in production. For an excellent reference, I recommend the bood "Beyond the Zone System" by Phil Davis. Bob Rapp [EMAIL PROTECTED] Bob - This message is from the Pentax-Discuss Mail List.
