Sony's S-Log3 Gamut Cine is a combination of the S-Log3 gamma curve and the S-Gamut3.Cine color space, often used as a picture profile in professional Sony video cameras. S-Log3 is a logarithmic gamma curve that captures a wide dynamic range, particularly preserving detail in the shadows and highlights to provide more flexibility during post-production color grading. On the other hand, S-Gamut3.Cine is a wide color gamut designed for cinematic applications, capturing a broader range of colors compared to standard spaces like Rec. 709. When used together, this profile allows for maximal creative freedom in post-production, capturing rich details in both luminance and color. However, it's important to note that footage shot in this mode will look flat and desaturated when viewed without color grading, as the profile is specifically designed to be manipulated in post-production.
