Hey, i've stitched together three photo's I took the other day using Photoshop CS's 'Photomerge' function, and while the results for the main image looks great, the sky isn't well merged in places, with angular distortion very visible. I've tried using the clone stamp to edit out this distortion, but due to the resolution of the image, the brush marks made by the clone stamp can be seen.
Any ideas as to how I can edit this distortion cleanly? Perhaps a filter I should be looking for?
TIA
