Oh it's actually really easy, open the two shots you want. Copy one and paste it on the other, then use the brush tool (soft edge, reduce the opacity of the brush) and brush out the bits you don't want! But practice lots!
don't send it back! Google, YouTube and TP will have answers! Otherwise hide it in a box for a month then try it again! Never send it back :bonk: Cracking prize though, I really need to take a peak at the POTY thing for another challenge next year!
Natural, I prefer number one. Nicely lit. Although I think I'd clone out the little white bit just at the bottom to the right of the fungi stalk, and crop/ clone the other little white bit on the trunk to the right! Nice DOF though.
I agree with Iain that the stag is lost a bit in the background and the grass in the foreground is a little distracting for me. I think you needed to ask the other deer to all shift their butts out the way!
I'm liking the sound of Clumber park! I still remember that macro course you did!
