Now you can see why the extra space at the sides was needed. Now
crop your image to tidy it up.
Well designed stereo cameras have this cropping built in by offsetting
the lenses slightly left and right from the exposed film frame.
If you are going to save your finished image as a JPEG for the
web, be careful with the amount of compression you choose as this
adds noise to the colours adding to the problem of ghosting.
