Hey Jackie, Is this Torres Del Paine? Also have you tried the patch tool for the lines or the clone overlay-both work pretty good for the line. The mountains and the water look neat! I'm not crazy about the outside lines-they look too busy,might be nice to choose the sky color and paint it over the lines. Just a thought.
BTW ,Jackie is a great sport and will be the judge for next weeks Theme-Mini Worlds!! So let's show her some support and post some really creative Worlds!!
I just had an idea to use the content aware scale to shrink instead of expand the canvas of an image then merge 4 different images that have been shrunk (of the same landscape but diff. views). I think then when you stretch it around w/ the polar co-ordinates it won't loose it's detail-I will try in AM as I'm on my laptop and don't have all my files.
