I would like to know how you see this development of this image that resisted me to be treated until reaching an acceptable result.

Thanks for your comments.

To me the same thing happens to me. It only works if I copy and paste the .xmp

I have detected a strange behavior in one of the Ansel modules. Specifically in the "Color calibration" module.

I have observed the following:

  1. I create a new instance of "Color calibration".
  2. I duplicate this instance for the B&W preset.
  3. I move the present over the "color balance RGB".
  4. I activate the present for B&W and in the "History" it is duplicated. Now I have two "Color calibration" with the same numeral "1".


Now if I don't like the result and I want to undo what I have done, I go to "History" select the initial instance of "Color calibration" and....


The instance that I had duplicated is placed at the beginning of the module group "color".


If I compress the "History" to leave it as at the beginning, it is still at the beginning. If I activate it, this happens:


It cannot be moved (Ctrl+Shift) and I can only delete it. Or close Ansel and reopen it. Only then the duplicated instance disappears.

I have tried the same with "Exposure" and it doesn't behave like that.


My Ansel is an AppImage, specifically:


If I am doing something wrong, I would appreciate your corrections.

Note: I often duplicate this instance because I like B&W and this module is very versatile. The reason for placing it above the "RGB color balance" is so that it affects all the lower modules with respect to the modifications I have applied to them. It is the last module I use in the transformation to B&W.

Thanks for reading and trying

Hi !

But, there is always a but...

In photos with speculars or areas with some saturated channel. I have my doubts...

Here is an example:image_transcoder.php?o=sys_images_editor&h=7&dpx=2&t=1679687757

This is the complete image

I am very happy and embarrassed.

Happy, because now I have a method very similar to the chemical one without breaking the flow referred to the scene.

Embarrassed that I did not achieve this result by my own means.

Thanks for your help.

This is the result:

Thank you. I'm going to try, and check my obsession that the whites are not colored

To match the ease of converting my B&W photographs to a tonal tonal shift such as Sepia, Cyanotype, Platinum, Selenium, etc., I have to use a tonal shift to convert my B&W photographs to a tonal shift such as Sepia, Cyanotype, Platinum, Selenium, etc.

I have only found with this tool that it allows to be worked by independent channels and allows the "scene mode".

Would it be acceptable in a scene mode workflow?

While trying to achieve a tonal shift using 4-way color balance, I noticed the following.

As I have not seen any reference in the Ansel or Darktable documentation, I ask if this is normal and what is the purpose of the percentage being so different between the different vias.

I leave an image

Any ideas or advice?image_transcoder.php?o=sys_images_editor&h=4&dpx=2&t=1679661785

I will try it and let you know if it works for me.

But it is not the same in terms of operability. With the "color correction" it was two clicks: set the white in the center and move the black to one of the color/tone boxes.

I will look for a solution and create a preset. I will comment if I find a good solution

Hello everyone,

I have a query. My photographic background comes from the days of chemical photography (not digital). We used to make use of toning to preserve prints (Selenium, platinum, sepia, etc.).

In DT I used to use the color correction module. Now obsolete in Ansel. This module had a virtue very appreciated by me because it allowed me to tacked the images without "tinting" the whites. In the current modules I have not been able to do this. They all end up "coloring" the whites. The tacking only attacked exposed and developed silver halides, the whites not having such halides, were not affected.  

Any suggestions?
