Canon DSLR C-Log vs Technicolor Cinestyle test
Unzip the file and use Canon EOS Utility software to install this picturestyle on your DSLR camera.
The biggest difference that is noticable between the two profiles is that one is brighter and other is darker, the grading way is also much different as for Cinestyle you need to darken the black tones and the mid tones slightly but the highlight is quite flat. While C-Log you need to only slightly darken the black tones and brighten the mid tones, but highlight still retains allot of details. Overall the dynamic range is very close to each other where the highlights gets blown out.
From what I see is that C-Log does it better when the conditions are quite harsh with a bright sky highlight and dark shadows the C-Log does it very well. But there it somehow have some issue with certain green colors where it looses detail in them. However in such harsh condition Cinestyle which flattens highlight too much just make allot of bright ares looks too flat and harder to regain the details without using a seperated grade over the highlighted area.
The only issue with C-Log is that it seem to loose details in the green, where as in the first shot can see in the grass it got less detail also in some of the trees, where the Cinestyle fairs much better with the details in the green.
So the conclusion if the sky and highlight details is important use the C-log, if you are filming a green field Cinestyle fairs much better with that.
