How to make a selection and create a layer from that selection

[Asterix00]

Like if I do a rectangle selection (rectangular marquee tool.) When creating a new layer from that selection, the part not selected become transparent. Like that for example. 

How to make a copy of the selected area on its own layer.

Thanks.

The best way is to

• crate the selection
• make a copy as new layer (this is the default if you duplicate or copy/paste)
• Use move tool to get the copy where you want it
• merge down the copied layer to the original layer.

Affinity prefers the principle of „non destructive edits“, meaning keeping everything in separate layers. but you can merge any time layer if you want to combine multiple layers back into one layer.

It is not clear from your post how you created the new layer. If the answers so far haven't helped, please provide more detail of the exact steps you're taking.

Hello walt.farrell. Thanks, usually in Photoshop Elements, I do the selection the Ctrl+J. And the selection only goes to the new layer.

That should also happen in Photo. Perhaps you can provide more-complete screenshots, including the complete application window and the Layers panel. Or a screen recording of the complete window, so we can see what's happening?
