Usually one wants to get rid off the background in a photo. In my case I want to get rid of the 'objects' of the photo and remain with a 'full background'. By full background I mean that I'd like to fill the spots where the objects where with what the background would have had. If the background is a solid color, then that's easy. I just draw a shape on top with the same solid color. But when the background is more complex, like the skyline, what do I do?
In my impression, it should be possible to 'extend' the background 'horizontally'. See this 49sec video for a demo. Any software/script/PS feature that does that? Any alternative solution? I'm trying to remove the skyscrapers from this image, and remain with skyline:
