Correct chromatic aberrations of raw images.
As this module operates on non-demosaiced raw data, the underlying model assumes an uncropped photographic image as input. It is therefore likely to fail when you zoom in, as it is only able to operate on the visible portion of the image. The module will therefore be bypassed at high zoom levels, and a “bypassed” message will appear at the top of the module. This limitation only applies to interactive work and not to the final export.
This module currently only works for raw images recorded with a Bayer sensor (the sensor used in the majority of cameras) – for other types of image, you should use the chromatic aberrations module instead.
The module will also not apply any corrections to any photos that have been identified as monochrome by their metadata, like the files produced by the Leica M10 Monochrom.
module controls
- itérations
- Le nombre d’itérations. Pour la plupart des images, « deux fois » est suffisant et correspond à la valeur par défaut. Parfois, l’augmentation de ce contrôle peut donner de meilleurs résultats.
- éviter les dérives colorées
- Si le module provoque une teinte violette, cochez cette case pour appliquer une correction.
