Unfortunately, most of the "auto" features don't work that way; they tend to be user actions which result in changes to the normal parameters of the module, and these static parameters are what gets stored in the processing history. A notable exception is the "automatic" mode of the exposure module, where the parameters become the ones defining the auto-adjustment (useful for things like "deflickering" time lapse images). This is the behavior you want, but the exposure module may not be suitable for general automated contrast-enhancement purposes, particularly because the black level control isn't set by the auto-adjustment... but you could check it out. Also, for whatever it's worth, there's instructions for doing something like what you describe with Gimp here: https://photo.stackexchange.com/questions/63692/how-can-i-get-a-uniform-white-balance-on-a-batch-of-jpeg-images/63704#63704 -- jys ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
