*****  You're talking apples and oranges... :-)  IF the originals only need
basic rotational fixing, rotation puts things *into* alignment, not out of
it, so the image is easier to view. It goes without saying that if you are
using slides, you may need to mask the absolute top/bottom/side edges so
things don't look *cockeyed*, *slanted*, or *mismatched.*

If you are working with prints, you trim or mask the edges after rotation.
Not even a beginner would have a hard time understanding how to make things
square again after correcting minor errors. If the errors are more than
minor or compounded with other errors, that's a different story. Rotation
alone won't fix it.
