-Prior to version 3.0 darktable's workflow was _display-referred_ (auto-apply pixel workflow defaults = "display-referred") and this option is still provided as a legacy mode. In this workflow, the [_base curve_](../../../module-reference/processing-modules/base-curve.md) or [_filmic rgb_](../../../module-reference/processing-modules/filmic-rgb.md) module performs tone mapping early in the pixelpipe and most other darktable modules operate on image data in the compressed _display-referred_ space.

 Selecting the display-referred workflow enables the legacy (pre-darktable-3.0) module order and automatically switches on the [_base curve_](../../../module-reference/processing-modules/base-curve.md) module for new images.
 
 Pixel data within the _display-referred_ space is non-linear and is not a physically realistic representation of the original scene. This can lead to various artifacts with some modules, hence the creation of the (now default) _scene-referred_ workflow.
 
 ## scene-referred workflow
 
-_Scene-referred_ workflow (auto-apply pixel workflow defaults = "scene-referred") was introduced as part of darktable 3.0. The module order was entirely rearranged to place the [_filmic rgb_](../../../module-reference/processing-modules/filmic-rgb.md) and [_base curve_](../../../module-reference/processing-modules/base-curve.md) tone mapping modules much later in the pixelpipe. This means that most modules now operate in _linear rgb_ space with only a few modules remaining within the non-linear _display-referred_ space. Within this workflow it is now recommended that the majority of image processing takes place using the modules up to and including [_filmic rgb_](../../../module-reference/processing-modules/filmic-rgb.md). Operations in this section of the pixelpipe, being truly linear, are much more physically realistic and produce fewer artifacts.

 In a scene-referred workflow many common tools (tone curves and levels, for example) are no longer useful ways to manipulate the image, since they rely on now-invalid definitions of black, white and gray. Experienced users may need to learn new techniques and discard old ones, but will be rewarded with much more robust and predictable outputs.

-    The _exposure_ module includes an automatic exposure adjustment of +0.7 EV (to provide a midtone brightening comparable to the +0.5 to +1.2 EV typically added by in-camera tone curves), and automatically enables the "compensate camera exposure" option for the filmic workflow. Both of these settings are intended to provide a reasonable starting-point for RAWs produced by a broad range of SLR and mirrorless cameras, but they can be overridden with an automatically-applied preset if the defaults produce consistently dark images for your camera.

Note that when using the color calibration module, the white balance module needs to be active and set to "Camera Reference" mode (this will be done automatically and warnings will appear if the two modules have inconsistent settings). When using both modules as prescribed, it is still possible to auto-detect white-balance from a specific area of the image by selecting the CCT picker tool in the CAT tab of color calibration.
