Open in a new window the picture of a pepper: File ? Open (ctrl+o).



Mark it out along its contours, choosing previously the Polygonal Lasso Tool.



Make a copy of it: Edit ? Copy (ctrl+c) and get back to the wallpapers window to insert the pepper on a new layer: Edit ? Paste (ctrl+v). Make the corrections on its size, applying the next selection: Edit ? Free Transform (ctrl+t).



We'll make the corrections on its brightness and contrast also, using the here shown option: Image ? Adjustments ? Levels (ctrl+l).



Mark out now a part of the pepper by using the Pen Tool and Make Selection command.
