I'am trying to get the Sony FS700 & A7S to closely match up in camera. This is because Im not good at colour correcting, so I'am looking to get them as similar as possible before post.
When taking them out for test's I had the exposure settings about the same, and both on the same white balance (kelvin). The a7s is on the 'Neutral' Creative style for all the following test's.
The first thing I tried on both camera's was PP7 with S-Log2, when I imported into Premiere CS6 they were pretty close. But the a7s colours seemed less natural and looked pretty green overall. I applied 3-way colour and RGB curves to try and match them but was quite tricky.
Second test I had both the pictures profiles off, this time they seemed to be better matched which I wasn't expecting. The colours still were not looking the same.
