![]() ![]() This slider is only visible if the exposure fusion feature is activated. A bias of 0 attempts to preserve the overall lightness of the image by combining both over- and under-exposed copies of the image. With a bias of -1, it is fused with underexposed copies. With a bias of 1 (the default), the image is fused with overexposed copies of itself. exposure bias (fusion) Determines how the multiple exposures are computed. exposure shift (fusion) The exposure difference between the merged images in EV units (default 1). mode The default behavior of this module is to correct lens flaws. Press the auto scale button (to the right of the slider) for darktable to automatically find the best fit. scale Adjust the scaling factor of your image to avoid black corners. For best results, use the exposure module to apply a suitable adjustment for correctly exposed highlights. To correct the aspect ratio of an anamorphic lens, use the rotate and perspective module. Double-cliquez pour basculer vers cette version et la modifier. Maintenez le bouton gauche de la souris enfoncé sur une miniature pour afficher temporairement cette version dans la vue centrale. Use this feature to compress the dynamic range of extremely underexposed images or for true HDR input. Le module gestion des clones liste, sous forme de miniatures, les différentes versions de l’image actuellement en développement dans la chambre noire. The resulting image is thus a combination of two or three different exposures of the original image. This feature allows you to merge the image with one or two copies of itself after applying the current base curve and boosting its exposure by a selected number of EV units. Each version can be edited independently without affecting other versions all versions use the same underlying image file, but the editing history of each. gamut check > duplicate manager View and create multiple versions of the current image. fusion Trigger the exposure fusion feature (see this Wikipedia article). darktable / Module Reference / utility modules / darkroom / duplicate manager < color assessment. Please refer to the curves section for more details about how to modify curves including the scale for graph and preserve colors controls. A second option in the preferences dialog allows you to choose whether darktable should attempt to apply a camera-specific base curve (if found) or the generic manufacturer one. This module will be enabled by default if preferences > processing > auto-apply pixel workflow defaults is set to “display-referred”. The resulting look up tables (LUTs) are editable by hand and can be created using the darktable-chart utility to match given input (such as hald-cluts and RAW/JPEG with in. The input to this module is a list of source and target points and the complete mapping is interpolated using splines. Camera-specific base curve presets are also available for some camera models. A generic color look up table implemented in Lab space. These presets are automatically applied according to the manufacturer ID found in the image’s Exif data. Simulate the in-camera JPEG by applying a characteristic base curve to the image.ĭarktable comes with a number of base curve presets that attempt to mimic the curves of various camera manufacturers. ![]()
