Remote control and offset

[Volker Schmidt]

The problem with many images is that they have stitching errors where
original photos are spliced together and the algorithm gets confused. I had
a collection of samples, but cannot find them right now. I have seen them
with different providers, even the the most reliable ones, i.e. the ones
that have near zero parallax errors.
