Downloaded the new Technicolor Cinestyle preset for the 5D Mark II today and tested it out on the field. I compared it to the Neutral Preset and the Super Flat (0, -4, -2, 0) Preset.
I love the preset. I get details in shadow areas that not even the Super Flat setting can achieve. Safe to say, it will be the new preset I will be shooting all my projects from now on.
I've made the video downloadable in full 1080p for those of you who want to see it in full res.
