Picture
Ok, so in the picture is a cutout of the swan sculpture, laid on top of an original painting...This was a quickie tryout, you can do the edges better if you take some time...(You can also cutout the middle section where the neck meets the body, or other holes like that too...)
  Ok, here's how...
1)On your Mac (sorry everybody else), open  the picture you want to cutout in Preview...
  See the "Select" button at the top of your picture? Go in to those choices & choose "Smart Lasso"...
  Then just draw a line all the way around the shape you want to cutout...(a thick line appears immediately)...(Once the shape is closed, like you have joined your beginning line to your end line, so it is a closed shape, the lines will change from thick paint line to a shimmering dotty line)...
  Now go to "Edit"...& choose "Invert selection", then choose "Cut"...
  Now you have your cutout shape!
  2) Now say you have saved your cutout image & now want to put it over top of a different background...Open the cutout image in Preview, select the Smart Lasso tool again, & go around your shape until you are back to your first lines & the shape is closed...Now go to Edit, & click "Copy", then open your new background image picture & click "Paste"...(just a heads up, make sure to close the first image, the one you copied from before trying to save your new pasted onto picture...)
  That is neat eh? & totally free if you own a Mac...
