I would like to make darktable auto apply lens correction to new images.
I created a preset and checked “auto apply this preset to matching images”.
It correctly applies the module to new images, and correctly adapt focal length, aperture and distance for the new image.
Unfortunately, it applies the scale parameter of the original image from which I created the preset, and I have to manually click on auto scale button.
Is this a desired behavior, or should I create an issue about this?
Without automatic scaling, it is better to manually enable lens correction for each image instead of manually clicking on auto scale in the auto applied module, but it would be far better to have the module auto applied with auto scaling.
The only preset you should use is to turn on the module. Otherwise you’re just copying settings around from the image you used to create the preset. This is the intended functionality at the moment.
@Luca_Fornasari I am not addressing your original question which has already been answered, but I personally would only recommend applying the lens correction to images where it is clearly needed rather than blindly to every image. My logic for this includes the fact that distortion correction will crop away part of the image. I use lens correction a lot when straight lines have become curved by lens distortion but this is not apparent in every image I shoot. Just a personal opinion that I am expressing. Good luck with DT. It is a great program made by a fantastic group of developers. Welcome to the forum.
