starless result in siril tif

If I make a starless and edit it with asingh transformation, then safe it as a tif and edit it in my photosoftware like , gimp, photoshop or any other and make a nice black background then in siril it is different.

I load the tif in SIRIL and the result is not black but terrible. attachment.

Am I doing something wrong here?

This is probably because you work on linear images which is not ideal for software like Photoshop or Gimp.
And also that depends on how are set the visualisation sliders and the display viewer.

Thans, I try again.

Hello
It didnt work, I strecht the image with Histogram autos strech.
I give the total workflow

It is very difficult to understand with this kind of screenshot.

We wrote something about it, on how to report issue: How to report issues — Siril 1.2.0 documentation

For example, I have absolutely no idea in which visualization mode you are displaying the images, or how are set the visualisation sliders.
