ABSTRACT
Now the only limitation you may run up against is Photoshop’s ability to align and blend strong geometric lines that come close to the camera lens. If the camera is hand-held to capture the component images (you have not used a specialized tripod head designed for professional panoramic stitching work) then the problem of aligning both foreground and distant subject matter is a big problem for any software (Photoshop handles it better than the rest). The camera should ideally be rotated around the nodal point of the lens to avoid something called parallax error. You will probably not encounter any problems with the new Photomerge feature unless you are working with strong lines in the immediate foreground. Notice how the curved lines in the image above are slightly crooked due to the fact that these images were shot with an 18 mm focal length and these lines are very close to the lens. Still pretty good - but not perfect.
