Some panorama tips and a correction

I have used hugin 0.7 for a while with the autopano-sift stuff. In
some cases it had troubles finding correct control points (e.g., in
the sky with moving clouds or on water). In these cases I often had
success by just removing the wrong control points and letting it work
I usually use exposure bracketing for my photographs. A cool
feature of hugin is that I can throw all the different exposures of
the component pictures into it and it will produce a nice panorama; I
can choose the exposure right at the end.
Hugin can also be used to produce high dynamic range pictures from
different exposures of the same szene, but I am still missing a good
program that then compresses the high dynamic range again into a
good-looking normal-dynamic-range image (often called tone mapping)
Despite the coolness of hugin, I currently use Microsoft
ICE for doing panoramas, and it's the only non-game program I run
on Windows; it's significantly faster than hugin and has an even
higher rate of success without manual intervention. But I miss being
able to control the exposure of the result, and it's proprietary.
The problem with just gluing two images together is
simple to understand: lenses distort.
Nitpick: The ideal lens projects a rectangle onto a rectangle
(rectilinear projection), and then one usually does not say that it
distorts. However, the rectangles of the images you want to glue
together have a different orientation, so they need to be transformed
in order to match even if the lens is ideal.
