Good Luck, Best Wishes!

- open the image you want to edit in photoshop
- duplicate the original image in the layers panel.
- then erase the original layer. you’ll just need the duplicated version.

-go to masking mode, shortcut key for this is “Q”.
-then use a brush, shortcut key is “B”.
- start to paint all over the background you want to remove.

(note:on masking mode the default color would be translucent red.)

- when you’re done painting the background you want to remove, switch to unmask mode. do this by pressing “Q”

(you’ll see all the selected area highlighted)

- hit the command for cut “ctrl+c”
- create a “new layer”, and work on that one
- hit paste “ctrl+v” (this would paste the previously cut image)

- get rid of the background by erasing the old layer.
- by then you should have the clean image without the background.

(if you commit some mistakes along the away, the command for “undo” is “ctrl+z”)

—————————————————————————–
OPTION# 2:
if you find the previous instruction too hard to follow, you could just use the eraser tool “E” then erase the entire background carefully… there you have it.

(but you’ll still have the best results using the first option)

goodluck
hope this helps
