just lined up 5 images shot in whatever that mode is where it shoots continuously (brain's gone blank) lined them all up on the big tree, then did layer masking to show all of the bits of sprog. clone dog's leg shadow where it disappeared from the image in the bottom right, crop. tadah!
If this doesn't make you smile, nothing will. I love it. The only thing I would change is the dog tail -- I think the composition would be better without it. You must have something really good for FS this month, if you're not using this!
Heh! You gotta watch what your feeding that sprog of yours - he's multiplying! Or maybe it's one of those strange time-space continuum things lurking in the woods.... Very fun shot and it did indeed make me smile!
