how to isolate objects by keeping the background

[Nessx]

By Isolating I mean encircling an object as if you want to cut it out but instead you just add an effect (e.g. color) to the encircled area. However the effect never applies to the chosen area.  How it will?

Do you mean that the effect applies to the entire image instead of being restricted to the chosen area, or do you mean that the effect isn’t applied at all?

Please tell us which Affinity app you’re using, and on what platform (Mac or Windows).

Oh hang on I tried it with adjustments and it is indeed restricted to the area. I misconstrued something because when I select an area with the selection tool and I type on fx (on the bottom right corner under layers) whatsoever none of this functions will apply to the selection. But glad I discovered that general adjustments do. Didn't try it after I noticed that functions fail.

But isolating an object  by keeping the background comes in handy and really important when u just want to add the tone mapping persona to a certain object in a photo- Do u know how to achieve this? 

[Nessx]

Maybe ther're different approaches for my several asked question but I simply would rely on the isolating like in After effects (

However he used already cut out objects. So I have to cut out my object export it and replace it on the photo. That's kinda dull that Affinity offers no other way but ty for ya Help.

Is that Designer or Photo? And why aren’t you using version 1.7.1??

[Nessx]

Photo and I'm designing it. 

My Mac is also at 10.14.3 but I'm just to lazy to upgrade to 10.14.5.  just my setting.

 

However it remains complicated. I just cut out the object and reattached it. the tone mapping on the general picture works but if I attempt it on the object it says it neesd a pixel layer in order to apply the effect. Any idea how I can convert the object to a layer?

Try the selection tools and masks or promote selection to layer.
