	candidating : Choose whether to prefer choosing candidate pixels (used to obtain color data) with segmentation analysis (high values) or inpaint opposed (low values). Click the button beside the slider to show the segments that are considered to have good candidates.
	rebuild : Choose how to rebuild areas that have all channels clipped. The "small" and "large" modes are tuned for segment sizes less than 25 and greater than 100 pixels in diameter, respectively. The "flat" modes attempt to ignore narrow un-clipped features (powerlines, branches) to avoid gradients. Finally, the "generic" modes attempt to find the best settings for each segment.
	"guided laplacians" mode and filmic's highlight reconstruction
	It is important to note that the _highlight reconstruction_ module is quite early in the pixel pipeline -- before [_input color profile_](./input-color-profile.md) and the full chromatic adaptation in [_color calibration_](./color-calibration.md) (if you use the _modern chromatic adaptation_ workflow). A common trick to solve clipped highlights is to simply desaturate them to white but, because white is not defined before the full chromatic adaptation and the input color profiling, it is not possible to use this trick here. Technically, there is no color yet at this point in the pipeline, only an arbitrary 3D signal.
	The _guided laplacians_ approach has been designed specifically to be immune to white-balance discrepancies and to avoid any concept or method related to color (so there is no explicit desaturation). It only handles gradients (transitions) in the signal and aims at connecting them smoothly, in order to fill the missing parts. This process is quite heavy though, since it falls into the category of supervised machine learning (gradient-based optimization through multi-scale curvature), which is a sub-branch of artificial intelligence.
	[_Filmic's highlight reconstruction_](./filmic-rgb.md#reconstruct) uses a simpler color propagation algorithm coupled with a desaturation option that can favor an _achromatic_ reconstruction. Not only does it _know_ about color (because it comes after the full color profiling and chromatic adaptation) but it also uses a simplified and faster version of the algorithm used by the _guided laplacians_ approach. Namely, this variant will not try as hard to restore details and will favor a smooth blur instead.
	The filmic reconstruction is good enough for very large clipped patches and offers the benefit of being able to degrade to white as a last resort. It is also better and faster to inpaint solid color into clipped areas, at the expense of details. Its main drawback is that it is not as selective in the source of the colors being inpainted in clipped parts, so it may inpaint unrelated colors.
	All in all, you are advised to use the _guided laplacians_ highlight reconstruction mode to:
	smooth the boundaries of clipped areas,
	recover spotlights and clipped areas of diameter below approximately 256px (on the full-resolution RAW),
	remove chromatic aberrations, which can occur during [demosaicing](./demosaic.md) (the next module in the pipeline) at the boundary between clipped and valid regions.
	If you find yourself having to increase the _diameter of reconstruction_ past 512px to get a full recovery from magenta, the best approach is usually to cap the diameter to 512px, do the most you can with this setting, and then enable filmic's highlight reconstruction to finish the work. This will give more bearable run-times with a very similar result.
	color balance
	A versatile tool for adjusting the image's color balance.
	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. For scene-referred workflow, you should consider using the improved [_color balance rgb_](./color-balance-rgb.md) module instead.
	overview	Yleiskatsaus
	The _color balance_ module allows you to shift colors selectively by luminance range (shadows, mid-tones, and highlights). It can do this using two different methods:
	lift, gamma, gain : The classic method, which allows a more separated control of shadows versus highlights.
	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.
	The _master_ settings affect the whole image. They are not available in _lift, gamma, gain (sRGB)_ mode. The slider ranges are limited to usual values ([50%; 150%] for saturation, [-50%; 50%] for contrast), but higher and lower values can be defined via keyboard input after right-clicking on the corresponding slider.
	For 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. The name of the mode can be use as a mnemonic to remember the order.
	The shadows parameter has a far heavier effect in _slope, offset, power_ mode than in _lift, gamma, gain_ mode. When switching from the former to the latter, you should adapt the saturation in shadows, dividing by around 10.
	Note: Although this module acts on RGB colors its location in the pixelpipe puts it into the Lab color space. Accordingly the module converts from Lab to RGB, performs its color adjustments, and then converts back to Lab.
	presets
	Several presets are provided in this module to help you to better understand how it can best be used. The "teal/orange color-grading" preset is a very popular look in cinema and is a good showcase model. It is meant to be used with two instances combined with [masks](../../darkroom/masking-and-blending/masks/_index.md). The first instance will exclude skin tones and will shift neutral colors toward teal blue. The second will partially revert the first one and add more vibrance to skin tones only. Together they will create separation between subject and background. The masking and blending parameters will need to be tweaked to suit every image.
	Other presets provide Kodak film emulations. In this way you can recreate any film look you like using _color balance_.
	mode : _lift, gamma, gain (sRGB)_ is the legacy mode from darktable 2.4 and earlier. In this mode, the color transformations are applied in sRGB color space encoded with the sRGB gamma (average gamma of 2.2).
	: _lift, gamma, gain (ProPhoto RGB)_ is the same as the previous mode but works 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.
	: _slope, offset, power (ProPhoto RGB)_ applies the ASC CDL in ProPhoto RGB space, encoded linearly. As with the previous mode, the RGB parameters are corrected in XYZ luminance internally. 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. All parameters will have some impact on the whole luminance range but the slope will mostly affect the highlights, the offset will mostly affect the shadows, and the power will mostly affect the mid-tones.
	color control sliders : This combobox selection affects the user interface used for the shadows, mid-tones and highlights controls.
	: _RGBL_ controls allow direct access to the RGB parameters that will be sent to the algorithm and internally adjusted in XYZ luminance, depending on the mode used. They are the only ones stored in darktable's development history.
