Mac Os 10.4.3 fixes Canon Raw file compatibility.

Several photography related fixes were included in the Apple's release of the upgrade for its Mac Os Tiger version 10.4.3.
OS level support for many RAW file formats now bug free. I was particularly happy to see support for both CRW and CR2 Canon Raw file formats supported in Finder, iPhoto and the Preview application. Also DNG format now has a better support by Apple applications. I believe that these fixes and new RAW file formats support were added by Apple in order for the new application for the photographers - Aperture, to work correctly, as the Aperture relies on the OS and its image format handling capabilities.
