I quite often use/abuse Hugin to align "found images";
for example aligning a modern photograph of a
building facade with a vintage photo.
If I find both images on the web, I am likely to have no
lens/camera parameters at all, and (in general) neither will be square on.
Despite this, Hugin's mosaic mode is clearly
general enough to handle this, assuming the facade
is indeed near enough flat.

However, in practice, optimising with so many variables
can be tricky, and prone to getting stuck in local maxima
(or is that minima) in the search space.
Can anyone recommend a reliable sequence of
which parameters to optimise/lock?
I'm assuming that the images should be added, optimised,
and locked one at a time.
