One briefly mentioned addition to the software bundle included with both the Canon EOS 40D and Canon EOS-1Ds Mark III is the new Picture Style Editor. This tool (as the name implies) allows you to edit and create custom Picture Styles based on the predefined ones (including color look-up tables). We've just updated our preview of the Canon EOS 40D to include a quick look at this tool and explore some of its features and functionality.
