AbelCine released a set of some very nice Scene Files for the Canon EOS C300 camera, and they also work on the C500. But for C100 owners, the camera won't accept the files. Thankfully, Texas Media Systems allowed me use of one of their C300 so that I could duplicate the files over by hand. These are exactly the settings of each single one plugged into the same settings on the C100 Custom Picture style list. The only exception was the White Balance G Gain setting, which was always "0" anyway, so I'm pretty confident that these transferred over correctly.
Of course, any and all differences in processing will result in a slightly different look than what would be seen on the C300, so test them thoroughly before use. Even so, they should be a great starting place for someone looking to play with these Scene Files on their C100.
