| Hi Guillermo, if I understand right, you are wanting to extract from an image, and first wish to duplicate the background so you can extract from it.
To copy the background, open your layers palette, and drag the background to the new layers icon (its at the bottom of the palette next to the bin).
There will now be 2 layers, background and background copy, and you can perform your extraction using the background copy. To save, do a "save as", and save as a PSD or TIFF file. |
