This example uses PhotoShop 6, with color settings similar to those used for the previous example. In addition, "Relative Colorimetric" was used instead of the PhotoShop default "Perceptual". These settings may be found under "Edit>Color Settings...".
As with example 1, there is no perceptible difference in the image, that I can see anyway, even after 10 conversions between RGB and CMYK and back again - 20 color space conversions total.
