    Interesting picture... you seem to have a speck of dust on your sensor, upper left corner :-)

    I did this for a member of the Panotools Newsgroup
    (tech.groups.yahoo.com/group/PanoToolsNG)
    It could be useful to many others as well.

    I knew there was dust on the sensor, but (even if it is a bit embarrassing) it does show very nicely how dust becomes more and more visible when the lens aperture decreases in size.
