Affinity Photo. Copying the shadow distribution onto a new layer?

[Franzi von Fragenfeld]

Hi,

I've got an image here, of which I need to recolor some areas of. In principle thats working well with HSL.
Still I have some areas which are in a very dark green tone wich in turn have some dark shadowed areas.

The new color I need to apply is a light grey.

Is it somehow possible to copy only some sort of "shadow value map" from the original image and apply it as a new layer?
So that I could select the complete green area, fill it with the paint bucket and than apply this "shadow" layer on top?

Thanks for any hints as how to proceed,

Fran

Not that i'm aware of, we certainly don't have any options for this.

If you can post a sample image, myself and the Forum regulars may be able to offer some further advice once we've seen the image

Don't know if this will help, but in the Select menu there's an option to Select Sampled Colour:

Click the colour you want to select and then click Apply to confirm the selection. Rather than using the paintpot, you can then add a Recolour adjustment layer which will automatically create a mask of the selection. Deselect to remove the 'marching ants', and then adjust Hue/Saturation/Lightness. It's also worth experimenting with the Opacity and Blend Mode settings.

But if you can post the original image, it'll be easier to understand the effect you want to achieve.
