Currently, if you click on the output image in brightness curve, the probe returns the value of the pixel in the output image and similarly for the input image, which is what one would intuitively expect. I don't see any easy way to override this behavior currently since the probe is owned by the c...

You are right, what I wrote is not what I meant.
I should have written:

When adding or moving an image compare transformation, whenever the output image is set to the input image, the downstream branch should not be recomputed.

There could be a way to specify that the value of the input point is desired, even when clicking the output point.
For example, when using the brightness curve transformation.

Yes, you are right that "Shift is already used to add new control points."

When creating a new mask after an upstream transformation, the downstream branch is recomputed.

When adding or moving an image compare transformation, for which the output image is set to the input image, downstream branch recomputations should not be triggered.

Considering that sliders have a fune tuning in their user interface : Fine Tuning . The method above is good for quick but coarse slider adjustments, but it can be tricky to get exactly the value you want. To make fine adjustments to the location of a marker, hold the Shift key down while dragging t...

Right clicking in image display area brings a menu. Add readout mode to the list, and make it the current pixel location for readout.
