Cine EI: Slog 3 and LUTs
The great advantage of shooting Slog 3 with the FX6 (rather than the
FS5 or Z90) is that you can import a LUT or use one of the built-in LUTs
to correct the image in the viewfinder (and the SDI and HDMI outputs).
Working with a LUT makes exposing the image much easier.
In this section, we will look at three options:
1. exposing Slog 3 with the built-in s709 LUT.
2. importing custom LUTs
2. exposing Slog 3 without a LUT.
