Please see my longer response about why doing this _in_ CMYK is usually wrong, premature optimization by using device dependendt color spaces if the result might go to many different printers, profiles etc. > As for the other things... > Modern Photographic work also relies on a higher bit depth.

Some of these are true, and GIMP is working towards lifting some of these limitations by migrating to GEGL. > There are also various selection tools, color adjustment tools and retouching > tools (such as the healing brush) that work better in Photoshop. These concepts do transfer to GIMP, and if one is generally empowering students with the ability to do manipulation on images.. teaching them how to do it with GIMP gives them both a skill and an option of a tool they can use without a fee; as well as have the freedom to improve in the other ways free software does. Pointing out that some things work better in Photoshop doesn't seem constructive in this discussion. /Øyvind Kolås -- «The future is already here.
