Delete selection is not fully deleting the selection

[Anirban3340219830sn]

The selection is not fully deleting when I press the delete button. it's still keeping a small soft line shadow like thing Inside in the middle of the selection not borders. I'm also attaching a image of the problem. Please help guys😓🙏

Difficult to see without seeing the original.

One way might be to Select > Subject, then press Q to select Quick Mask Mode and paint back in the missing bits (press X to go back and forth), then Q again to go back to the selection.

Here's the original pic. I simply used object selection tool (lasso) to select the subject then I inversed the selection then I simply pressed delete but that didn't fully deleted the contents of the selection. I thought those things happen only in borders for fading purposes why it kept things literally in the middle of selection 😐

Having made your selection, as described, you would apply a Layer Mask to apply the cut-out (and it would also be non-destructive).

Before & after layer masking the selection. Same problem persists. See the robots left leg

Use a grey gradient (mask) to soften the transition.

You could also use curves or levels while in Quick Mask, to harden up any soft transitions.

I would probably start with the above and hide with a layer mask as Derek has said.

I would then Ctrl Click to load the mask as a selection, and use Select > Modify > Expand  with a value of 1 pixel, and manually paint out the fringe with black in the mask.  Then repeat if the 1 pixel did not clear it.

I had a quick go this morning using some of the techniques I mentioned.

Is this the kind of thing you want to do?

No no I was just trying to make pngs but it's ok I already solved my problem, still thank a lot for helping me. 🙏

If you make it none-destructive it's easy to change it to, for example,  a PNG with a transparent background.
