Right I tried to follow the tutorial I think itll basically work in  Its extrahera not a command Id ever have selected sponaneously in my life I think Ill be able to do it although tonight Ive been spending a lot of time without tangible results The tool is kind of too intelligent for what I tried to do I outlined the part I wanted with green and filled inside with blue but then Photoshop tried to guess quite wrongly what I really wanted and kept big blurry bits of the greencovered stuff too  Computers are just too smart these days Anyway I made progress Ill probably get there another day Thanks David
