How can i save an extracted image to be able to edit it

A really simple method is to use the quick selection tool to outline a person or object in a photo. Holding down the alt key changes the tool action from plus to minus - so you can perfect your selection as you go along (e.g. if you accidentally select part of the background)

When you are happy with your selection of the person or object press Ctrl+J - this will automatically create a new transparent layer with your selection as shown by the checkerboard background.

You can then add any other picture or background - here I’ve used a simple green background to illustrate the point by selecting Layer > New Fill Layer > Solid Color

I then clicked on the transparent layer in the layer pallet and dragged it to the top - to reveal the green background behind my person selection.

I then selected the hand tool and the bounding box appeared - by holding down the shift key you can drag the corner handles or sides of the bounding box to resize and then click the green checkmark to confirm OK. You can then drag the image to any position in the frame of your chosen background. Save as PSD to keep your layers for later or click Layer > Flatten Image to save as Jpeg.
