Ever since Canon released the “Studio Portrait” and “Snapshot Portrait” Picture Style files on the 19th of November, 2007, it has become a very viable option for shutter bugs to just select these settings instead of going through the tedious process of doing everything themselves.
Included in the bundle 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). Such files can be found in the link below.
