i use cs4 to stitch pano shots and lately ive been having some real issues with the 'straightness' of the shots.
I have got some great shots taken of city skylines and use photomerge to slice them together and find that the horizon's are all sloping away (down to the left or right).
Ive done my best at ensuring that i take the photo's at the same level but still cant stop the processing coming back with a sloping horizon.
What am i doing wrong?
