Me on skis. Bet you can't see where Dave's finger was blocking part of the snow. I don't usually alter pictures aside from basic editing, but I liked this version and wanted it to look nice. You can see the original or find out how I fixed it here.
Basically, I created a new layer in the GIMP and pasted a rectangular section of snow into the area I wanted to reconstruct. I then added a black layer mask (full transparency) and colored in the area over the missing section so that the copied snow would show through. I used a fuzzy brush around the border so it would blend into the original, then adjusted the contrast so you couldn't see the difference. Made a few minor snow tweaks with the heal tool and you see the result.
