	To understand the parameters of the local laplacian filter, one can think of it as applying a curve to the image, similar to the following graph:	Para comprender los parámetros del filtro laplaciano local, se puede pensar en aplicar una curva a la imagen, similar a la siguiente gráfica:
	![local laplacian curve](local-contrast/local-laplacian-curve.png#w33)	![local laplacian curve](local-contrast/local-laplacian-curve.png#w33)
	This curve is applied to the image in a way that works locally and avoids halo artifacts.	Esta curva se aplica a la imagen de una manera que funciona localmente y evita los artefactos de halo.
	The local laplacian mode also supports shadow lifting and highlight compression, similar to the [_shadows and highlights_](shadows-and-highlights.md) module.	El modo laplaciano local también admite el levantamiento de sombras y la compresión de resaltes, similar al módulo [_sombras y luces_](shadows-and-highlights.md).
	detail : Add or remove detail. Higher values increase local contrast. This inserts an S shaped element in the center of the curve, to increase or decrease local contrast.	detalle : Agregue o elimine detalles. Los valores más altos aumentan el contraste local. Esto inserta un elemento en forma de S en el centro de la curva, para aumentar o disminuir el contraste local.
	highlights : This affects one end of the S shaped contrast curve, effectively increasing or compressing contrast in the highlights. A low value pulls the highlights down.	luces : Esto afecta a un extremo de la curva de contraste en forma de S, aumentando o comprimiendo efectivamente el contraste en las altas luces. Un valor bajo reduce las luces altas.
	shadows : Similar to the highlights parameter, this affects the other end of the contrast curve, and increases or decreases contrast in the shadows. A higher value gives more contrast in the shadows. A lower value lifts the shadows and can effectively simulate a fill light. Note that this is done with local manipulation of the image. However, this means that a completely dark image cannot be brightened in this way -- only dark objects in front of bright objects are affected.	sombras : Similar al parámetro de altas luces, esto afecta al otro extremo de la curva de contraste y aumenta o disminuye el contraste en las sombras. Un valor más alto da más contraste en las sombras. Un valor más bajo levanta las sombras y puede simular efectivamente una luz de relleno. Tenga en cuenta que esto se hace con manipulación local de la imagen. Sin embargo, esto significa que una imagen completamente oscura no se puede iluminar de esta manera; solo se ven afectados los objetos oscuros frente a los objetos brillantes.
	mid-tone range : This controls the extent of the S shaped part of the contrast curve. A larger value makes the S wider, and thus classifies more values as mid-tones and fewer values as highlights and shadows. In higher dynamic range settings it can be useful to reduce this value to achieve stronger range compression, by lowering the contrast in the highlights and the shadows. Note however, that for really strong HDR scenarios this may work best in combination with a [_base curve_](./base-curve.md) that pre-compresses the range, perhaps with an approximately logarithmic curve. The exposure fusion feature in the [_base curve_](./base-curve.md) module may lead to more pleasing results at times, but is also more prone to halo effects.	rango de tonos medios : Controla la extensión de la parte en forma de S de la curva de contraste. Un valor mayor hace que la S sea más ancha y, por lo tanto, clasifica más valores como medios tonos y menos valores como luces y sombras. En configuraciones de rango dinámico más alto, puede ser útil reducir este valor para lograr una compresión de rango más fuerte, reduciendo el contraste en las luces y las sombras. Sin embargo, tenga en cuenta que para escenarios HDR realmente fuertes, esto puede funcionar mejor en combinación con una [_curva base_](./base-curve.md) que precomprime el rango, quizás con una curva aproximadamente logarítmica. La función de fusión de exposición en el módulo [_curva base_](./base-curve.md) puede dar lugar a resultados más agradables en ocasiones, pero también es más propensa a los efectos de halo.
	: This setting can cause banding artifacts in the image if pushed to extreme values. This is due to the way in which darktable computes the fast approximation of the local laplacian filter.	: Esta configuración puede provocar artefactos de bandas en la imagen si se empuja a valores extremos. Esto se debe a la forma en que darktable calcula la rápida aproximación del filtro laplaciano local.
	sigmoid	Sigmoide
	Remap the tonal range of an image using a modified generalized log-logistic curve.	Remapea la gama tonal de una imagen usando una curva modificada logarismica.
	This module can be used to expand or contract the dynamic range of the scene to fit the dynamic range of the display.	Este modulo se puede usar para expandir o reducir el rango dinámico de la escena fotografiada (imagen RAW) al rango dinámico de la pantalla.
	Note: Modules placed before sigmoid in the pipeline operate in [scene-referred](../../../darkroom/pixelpipe/the-pixelpipe-and-module-order.md/#scene-referred-workflow) space. Modules after sigmoid work in [display-referred](../../../darkroom/pixelpipe/the-pixelpipe-and-module-order.md/#display-referred-workflow) space.	Nota: Los modulos colocados antes de sigmoid operan en [scene-referred] (../../../darkroom/pixelpipe/the-pixelpipe-and-module-order.md/#scene-referred-workflow). Los modulos colocados despues de sigmoid operan en [display-referred] (../../../darkroom/pixelpipe/the-pixelpipe-and-module-order.md/#display-referred-workflow).
	usage	uso
	Please take note of the following guidelines while using this module within your workflow:	Tome nota de los siguientes consejos cuando utilize este modulo en tus desarrollos.
	only use one display transform : Never use sigmoid together with another display transform module (i.e. [_filmic rgb_](./filmic-rgb.md) or [_base curve_](./base-curve.md)).	Al revelar los negativos de película escaneados/fotografiados, se recomienda que desactive cualquier módulo de mapeo de tonos como [_película rgb_](filmic-rgb.md) y [_curva base_](base-curve.md).
	adjust for the mid-tones first : The sigmoid curve pivots around middle gray. Before using sigmoid, you should first use the [_exposure_](./exposure.md) module to adjust the mid-tones to your liking.
	less is more : You should try to accomplish the majority of your processing using modules in the scene-referred section of the pixelpipe and not rely on the display transform module (_sigmoid_, _filmic rgb_, _base curve_) to do all the work.
	preserve hue to taste : This module provides a number of methods to preserve hues. You are advised to use the "per channel" mode and tune the hue preservation to your liking on a per-image basis. Sunsets and fire are two examples where users commonly reduce the hue preservation to achieve a "hotter" look.
	keep skew at bay : For images like portraits, it is best to refrain from using skew values above zero. This way you will avoid harsh transitions in the skin tones. This is particularly important when hue preservation is not enabled, as the skew also affects the hue path of the skin tones.
	contrast : Adjust the aggressiveness of the compression while leaving middle-gray unchanged. Higher values require lower exposure to reach display white, and shadows become darker. Lower contrast is able to display a larger dynamic range.
	skew : Lean the compression towards shadows or highlights. Skew can be used to transfer some contrast from shadows to highlights or vice versa without changing the amount of contrast at middle gray. Positive skew flattens shadows and compresses highlights. Negative skew creates darker shadows and duller highlights.
	color processing : The mode used to map pixel values from scene to display space. : - _per channel_ mode applies the sigmoid curve to each rgb channel separately, affecting luminance, chroma, and hue. Hue can be optionally preserved using the _preserve hue_ option (below). This mode is in line with the behavior of the color layers in analog film, and handles smooth roll-off to bright areas very well. : - _rgb ratio_ is similar to _preserve color_ in [filmic rgb](./filmic-rgb.md). It maps the rgb triplet uniformly using the sigmoid curve, which preserves the spectral color of the pixel. Bright colorful pixels are desaturated along spectral lines as they would otherwise end up outside the display gamut.
	preserve hue _(per channel mode only)_ : Choose how much to preserve hue -- 100% preserves the spectral hue of the image (identical to using the "rgb ratio" color processing mode); 0% uses the per-channel mode with heavy hue skewing (see below). An acceptable approximation of preserved perceptual hue is usually somewhere between the two extremes. : All colors that lie between the primary colors (red, green, and blue) converge towards the closest secondary colors (yellow, magenta, and cyan). The _per channel hue skew_ effect creates yellow sunsets and fires, magenta-looking blue lights, and cyan skies. The skew is stronger for brighter and more saturated pixels.
	target black : Lower bound that the sigmoid curve converges to as the scene value approaches zero -- this should normally be left unchanged. You _can_ use this to give a faded analog look, but should instead prefer to use the "global offset" slider in [_color balance rgb_](./color-balance-rgb.md) to achieve a similar effect.
	target white : Upper bound that the sigmoid curve converges to as the scene value approaches infinity -- this should normally be left unchanged. You can use this to clip white at a defined scene intensity.
	primaries	primarias
	Expand this section to set custom primaries. You are advised to use the "smooth" preset as a starting point and then adjust using the following controls:	Expanda esta seccion para establecer primarias. Se recomienda que utilize el "smooth" preset para empezary y despues ajuste usando los siguientes controles:
	Note: These settings apply only to the _per channel_ processing mode.	Nota: Esto parametros solo applican al modo de processar _por canal_
	base primaries : Choose the set of primaries to use as the base for adjustments. This is a bit like locally overriding the working profile, and is necessary to allow presets to be created that don't change even if the user amends the working profile used in the pixel pipeline.
	red/green/blue attenuation : Attenuate (decrease) the [purity](../../special-topics/color-management/color-dimensions.md#definitions) of the red/green or blue primaries before the signal is processed through _sigmoid_'s per-channel curves. An important consequence is that now even the brightest and most pure inputs get smoothly degraded to achromatic at the high end. This avoids posterization and flat-looking patches, which are often seen with, for example, blue LED lights.
