These BASE LUTs sets the correct contrast, saturation and gamma levels for the different cameras without loosing information in highlights or shadows – no whites are clipped and Superwhites (video signals over 100% IRE) are scaled to 100% IRE to expand dynamic range even further. Blacks are lowered to the lowest possible – with all shadow details preserved without crushing the blacks.
All Sony LUTs are gernerated based on precise light meter (Sekonic L-408) readings with a standard grey-card. Base exposure was the light meter reading with additional stops overexposure depending on the selected gamma’s needs, so that colors and contrast look right.
This LUTs are needed for footage filmed with cameras like Sony FS7, FS5, A7S and all which are using Picture Style Gamma s-log, slog2 and s-log3.
Expose s-log +1 stop over. When filming s-log2 or s-log3 expose +2 stops over to get correct brightness with this gamma settings.
