Using LUTs in shooting
Look-up tables (LUTs) are used in image color conversion.
Log gamma movies are harder to monitor at the time of shooting because they have lower contrast than usual. For normal contrast and clearer display on the monitor or viewfinder, you can apply a LUT at the time of shooting. This is helpful in subject checking, focusing, and other precise camerawork. It also makes it easier to visualize from the shooting stage how your work will look after color grading.
LUTs applied at the time of shooting can be embedded in the metadata of recorded video files, so you can also use them in post-production.
Besides the preset LUTs, you can import your own LUTs (in the .cube format) to your camera.
Appearance of S-Log3 with ISO/EI applied
|s709||Film-like color tones and color reproduction, with low contrast|
|709 (800%)||Color reproduction and high contrast suitable for TV broadcasting|
Up to 16 LUTs can be imported.
