Darktable mask parameter hsl skin#

In this mode, the slope parameter acts as an exposure compensation, the offset acts as a black level correction, and the power acts as a gamma correction. As with the previous mode, the RGB parameters are corrected in XYZ luminance internally. Slope, offset, power (ProPhoto RGB) applies the ASC CDL in ProPhoto RGB space, encoded linearly. In this mode, the RGB parameters are corrected in XYZ luminance (Y channel) internally so they affect only the color, and only the “factors” adjust the luminance. Lift, gamma, gain (ProPhoto RGB) is the same as the previous mode but works in ProPhoto RGB space, encoded linearly. In this mode, the color transformations are applied in sRGB color space encoded with the sRGB gamma (average gamma of 2.2). 🔗module controls mode lift, gamma, gain (sRGB) is the legacy mode from darktable 2.4 and earlier. In this way you can recreate any film look you like using color balance. Other presets provide Kodak film emulations. The masking and blending parameters will need to be tweaked to suit every image. Together they will create separation between subject and background.

The second will partially revert the first one and add more vibrance to skin tones only. The first instance will exclude skin tones and will shift neutral colors toward teal blue. It is meant to be used with two instances combined with masks. The “teal/orange color-grading” preset is a very popular look in cinema and is a good showcase model. Several presets are provided in this module to help you to better understand how it can best be used. Accordingly the module converts from Lab to RGB, performs its color adjustments, and then converts back to Lab. Note: Although this module acts on RGB colors its location in the pixelpipe puts it into the Lab color space.

When switching from the former to the latter, you should adapt the saturation in shadows, dividing by around 10. The shadows parameter has a far heavier effect in slope, offset, power mode than in lift, gamma, gain mode. The name of the mode can be use as a mnemonic to remember the order. The slider ranges are limited to usual values ( for saturation, for contrast), but higher and lower values can be defined via keyboard input after right-clicking on the corresponding slider.įor better efficiency, in slope, offset, power mode it is recommended that you set the slope first, then the offset, and finally the power, in that order. They are not available in lift, gamma, gain (sRGB) mode. The master settings affect the whole image. slope, offset, power The new standard defined by the American Society of Cinematographers Color Decision List (ASC CDL) and more suited to scene-referred editing. It can do this using two different methods: lift, gamma, gain The classic method, which allows a more separated control of shadows versus highlights. The color balance module allows you to shift colors selectively by luminance range (shadows, mid-tones, and highlights). For scene-referred workflow, you should consider using the improved color balance rgb module instead.

This module can be used to revert parasitic color casts or to enhance the visual atmosphere of an image using color grading, a popular technique in the cinema industry. A versatile tool for adjusting the image’s color balance.
