Below are illustrated explanations of each curve. Lab Adjustments provides a wealth of curves to alter the look of the image.
RAWTHERAPEE TONE CURVE SKIN
When enabled, the effects of the Chromaticity slider and the CC curve will not be applied to skin colors, so that you can increase the chromaticity of your photo without causing skin to appear oversaturated. When enabled, it restricts the effects of the Lightness According to Chromaticity ( LC) curve, so that you can make skin fairer (by increasing the lightness of the skin) without affecting the model's clothing or background. For backwards compatibility, when opening processing profiles where " B&W toning" was used, the Chromaticity slider will get automatically set to -100, providing the same effect.įits the colors of the image into the gamut of the working color space and applies Munsell correction to retain color purity. The " B&W toning" checkbox is deprecated from version 4.0.12 and is replaced by the Black-and-White tool located in the Color tab. The best way to convert an image to black-and-white is by using the dedicated and powerful Black-and-White tool in the Color tab. Setting this slider to -100 removes all color, making the image black and white.

The Lab Chromaticity slider increases or decreases the chromaticity of the image, by applying a contrast curve to the a- and b-channels of Lab space. Tonalities above the average are lifted (lowered), while tonalities below the average are lowered (lifted). In developer's terms: this slider applies a contrast curve centered at the average lightness level. The contrast slider in Lab increases or decreases the contrast of the photo, again applied to the L-channel. As with the brightness slider in the Exposure section above, the black point and the white point do not move. When using the Lightness slider in the Lab section, a tone curve is applied to the L-channel of the Lab color space.
