Sony S Log2 To Rec 709 Lut

The second LUT is almost exactly the same as the first LUT, but has one change. It keeps the video code values in the Rec.709 broadcast safe legal range. If you use this LUT, you should take great care to expose correctly in-camera. Color grading LUTs for DJI, Canon, GoPro, Sony, Blackmagic, Panasonic and more. Film style LUTs for color grading in DaVinci Resolve, Adobe Premiere, Final Cut Pro, Photoshop, and After Effects! Emulate the look of film, quickly color correct S-Log 2, S-Log 3, Technicolor Cinestyle, D-Log, Protune, and LOG styles.

Using Picture Profile presets with S-Log

When shooting in S-Log, use Picture Profile presets PP7, PP8, or PP9.

The PP7 preset combines S-Gamut and S-Log2, while PP8 is S-Gamut3.cine/S-Log3 and PP9 is S-Gamut3/S-Log3. Here, select PP7 (S-Gamut/S-Log2) and leave the preset details as-is. A distinction of this Picture Profile, intended for subsequent color grading, is a gamma broad enough for movie production.

Why Log video looks faded and low-contrast

Sony S Log2 To Rec 709 Lut File For After Effects

Often, gamuts used in professional video applications conform to ITU-R BT.709 (Rec. 709), established for HDTVs. This is illustrated below.

Here, the curved color space represents the range of human vision. The gamut of Rec. 709 is much narrower. In contrast, it is easy to appreciate how much broader S-Gamuts used in S-Log recording are.

When viewed on a screen designed for Rec. 709, Log video lacks contrast because the screen cannot display the full gamut.

The ITU-R BT.2020 gamut outlined in green can be reproduced by 4K equipment. This shows how much broader your creative palette is in 4K than in HD.

Easily reproducing colors on Rec. 709 screens with 3D LUTs

Optimal display of Log video on Rec. 709 screens requires color grading, when you will use lookup tables (LUTs). This conversion prepares the material for display on Rec. 709 screens.

Rec 709 To Log Lut

Unlike 1D LUTs, which mainly adjust luminance, 3D LUTs control hue, saturation, and brightness of each RGB color. LUTs simplify color grading, because without them, instant S-Log video display matching the gamut of Rec. 709 screens would be difficult as you adjust tone curves, hue, saturation, and other details two-dimensionally.

When ILCE-7SM3 has recorded movies in the [S-Log3] gamma and S-Gamut3.Cine under Color Mode or S-Gamut3 under Color Mode, you can use this LUT.

Using Gamma Display Assist and external monitors

To make it easier to check S-Log video on a Rec. 709 screen as you shoot, use Gamma Display Assist to apply LUTs. The contrast of viewfinder and monitor display will look as if you were not shooting in S-Log. In this way, Gamma Display Assist enables precise camerawork, whether you are checking subjects or adjusting the focus.

You can also take advantage of LUT-compatible external monitors, which are now more common.

This video introduces shooting in S-Log and shows how effective it can be.

When shooting in S-Log, you can choose S-Log2 or S-Log3. Colors are reproduced differently depending on your choice, so use the right option for your workflow.

In this video, you can see how S-Log2 colors differ from those of S-Log3.
