"Image Treatment" and "Blur Background"

[dalo.53 Profile Website]

I often use "Area Treatment" to mask a background area to change the exposure. I then add a second step to "Blur Background". This requires that I create two identical background masks.
Is there any way I can create a SINGLE background mask to accomplish both steps? I've attached "Before" and "After" pics to better explain.

Sure you can!
Use the Select Area tool and choose Background, now make your background selection, finish and choose an Brighten effect, see image below

(You can also greate your own effect and drag in a Tone node to use the exposure slider if you wish to use exposure instead of brightness.)

When applied the effect, hover above the effect gallery and a window will pop-up with an selection Background, click on this selection and choose your next effect (blur) you can re-use the mask endless!

Tip:
Open your first background effect in the effect editor (rightclick the effect tab and choose Manual Edit)

and drag in a Invert Selection node as the image below shows

You can rename the node to Subject if you wish (you will see all effects that are designed for Subject first in the gallery)

By this you will have a new selection while hovering above the effect gallery, Not Background (or Subject) and you can use this selection to add an effect to the opposite of the background

Succes,

Edit:
If you use Area Treatment first, there will be a selection in the pop-up window as described above with a name Area1, I guess this number will increase with every new Area you add with the Area Treatment tool.
So you can still use your own strategy, only you don't have to paint the selection again for the blur, just hover above the effect gallery and choose for Area1 and apply a blur
