These options control some of the internals processing of darktable.
Si se activa esta opción, darktable utilizará las librerías Little CMS 2 del sistema en vez de sus propias rutinas. Esto es significativamente mas lento que la configuración por defecto, pero le dará unos resultados mas exactos en algunos casos (encendido por defecto).
Tenga en cuenta que si el ICC dado está basado en la tabla de búsqueda (LUT) o contiene ambos, LUT y una matriz, darktable utilizará Little CMS 2 para representar los colores independientemente del valor de este parámetro de configuración.
El interpolador de pixel se utiliza en la rotación, corrección de lentes, aumento y reducción de escala; las opciones son “bilineal”, “bicúbico”, “lanczos2”, “lanczos3” (por defecto).
Set folder that contains Lut files used by lut 3D module. (need a restart)
With that setting, you can define which default workflow to work on. Two workflows are available:
Scene-referred workflow is based on linear modules and will auto-apply filmic and exposure. This workflow consist of adding, by default, +0,5 EV of exposure (in exposure module), to adjust the global brightness and mid-grey to a similar value to that used by most JPEGs produced by SLR cameras. The interest of filmic is to apply a tone mapping curve at the end of the pipeline, allowing a physically realistic retouching on RGB values encoded linearly before, but also to manage color consistency through the tone mapping, in order to preserve hues as much as possible and to avoid gamut overruns.
This default +0,5 EV value can be overridden using an auto-apply preset if it is found the images from a particular camera are consistently too dark.
The scene-referred workflow also enables by default the "compensate camera exposure" option in the exposure module, to adjust the global brightness appropriately in cases where the camera's exposure compensation dial was used to protect highlights in the image or Expose To The Right (ETTR) to optimally make use of the sensor's dynamic range.
Display-referred workflow, used by default, is based on Lab modules and will auto-apply base curve and the legacy module pipe order (darktable 2.6 and older). It will apply the non-linear transformation at the beginning of the pipeline, and all editing will then be done on non-linear RGB.
A third option is available to not use any workflow and so deactivate all automatic modules. That allow you to manage your pipeline manually.
Utilice el preajuste de curva base de la cámara por defecto en vez del genérico del fabricante, si existe uno disponible. Para mayores detalles vea la Sección 3.4.1.5, “Curva base” (apagado por defecto).
Este aumento de la nitidez no se recomienda en las cámaras sin un filtro de paso bajo. El valor predeterminado es no añadir ningún tipo de nitidez automáticamente ya que la mayoría de las cámaras más recientes no tienen un filtro de paso bajo. (necesita reiniciarse)
If switched on, darktable analyses the preview image available via exif data during import or refreshing exif for being monochrome and sets the darktable|mode|monochrome tag accordingly. As this reduces performance it is turned off by default. Turn on for better monochrome image workflow support.
