Diane - I'm not the world's expert at cloning or knowing what you can do with what software package. But that seems a huge task. It would be fine if you had a background with a flat tone. But you've got such a variety of light and shade and colour in the water and then on the bird with the fish, that trying to match everything in order to hide that wing would, for me, be an impossible job.
I'm afraid I'd write it off as undo-able (which, of course, will just prompt someone to prove me wrong)
Great capture to hone your PP skills on Diane! It'll take some practice but Mike's efforts can give you an idea of what can be accomplished.
Nice job, Mike! You're really getting good at this!
Wow! Thanks Mike it can be done I can't wait to give it a try. I think it will probably take me a while but will definitely be worth it in the end.
Great capture and the clone fix worked very well.
