I have a panorama created from three separate images. As a result of perspective, there's an area that I need to fill seamlessly to match existing deep blue sky:
I've tried content-aware fill but it doesn't really have enough to work with and pulls in pixel data from the building as well as blue sky. I also tried using a gradient fill but there's enough variation horizontally at the sky edge that I can't get a good match.
Can anyone suggest how to fill the empty area so it matches the adjoining sky seamlessly?
