Have a square .jpg photo with black background; I want to make it longer by adding additional black to the bottom in order to make create a rectangular photo. Then want to overlay text on the added portion (new layer?). How? Thanks - appreciated!
And yet another way - have black as the background color chip in the toolbar. Use the crop tool set at No Restriction: drag a crop box over the whole image, release but do not commit. Then drag the bottom handle down as much as you want to add. Tap the Enter key.
