Each of the images is slightly different as outlined by the following table: FileName ToneRange HalftoneHints pics/jim___cg.tif A Y pics/jim___dg.tif B N pics/jim___gg.tif B Y The images with tone range A are 0-100% linear reflectance images, in other words, fixed full gamut tone range. The images with tone range B are what we call "normalized", meaning that the image has been tone adjusted such the Highlight and Shadow are at gray levels 1 & 2**BitsPerSample-2. Each of the three grayscale images should be rendered to look like the halftone in pics/jim___ah.tif when printed on a Canon SX engine.
