Well, every background extraction is tricky - I tried PhotoshopCS 4
tools - they seems to be trivial to use and seem to be easy - but for
a complex task which need a lot of pixel precision you have to do a
lot of manually corrections too so the final feelig is a kind of
frustration - (with gimp magic wand progresive selection feature [drag
over layer left / right], I can do the same thing quicker).

In comparison with Photoshop - Jenny demos look perfect especially the
tree. I hope the final tool will extract selection / selected colors
direct (not just select pixels).
