I recently got PSPx6 [and a moment ago it was updated to the 64-bit version whatever that does for us
] and one of the new tools is 'Smart Selection Brush' and I have been wondering how well it would work. The pigeon seemed a good test.Just by waving the mouse over the bird I got most of it selected with the bright area of the wing a second sweep ... You seem to just move the mouse roughly over the area to be selected. Only problem I didn't pick up its beak and that was a little tricky but I got there without the need for a layer mask.
Copying just the selected area and pasting as a new layer then resizing the new layer but not the basic picture and a merge to finish has this.... copying and working on a posted jpg is not ideal but it gives you the idea.
My reason for the size change is that the bird and cyclist seem much of a similar size so working from the idea that two things [ evens] is not good the resize turns it into a single plus something else [odds are good
]
The more I look at this the more I think it is one of your best I have seen.
