  I want to vectorize land forms from an ortho image, so I make a new
 polygon shape file and create new objects inside it. When I follow the
 outline of the land form, I have the problem that the new polygon covers
 the underlying layer (it is red and only slightly transparent), so I
 cant see the structures of the ortho image anymore. Is there a way to
 create new polygons, but only have the border of the polygon drawn while
 creating it? I couldnt find such an option in QGIS.

 You can change the colour of the rubber line. I have changed the alpha
 channel to 100.
