Just a quick reminder that we are having 'The Aftermath' for the Panorama Project on the 16th June. The idea is to take a set of images of a scene and stitch them together to make some sort of panoramic image. You can use whatever stitching method you prefer. Photoshop does a good job for most panoramas but Hugin, the free software John talked about, usually does a better job AND you can choose different projections to suit the picture.
You can find Hugin at http://hugin.sourceforge.net/ The new 2011.0.0 version has just been released, it is available ready to use on 32 and 64 bit Windows and Mac (there is a know issue on Mac OS10.5 although there is a usable workaround). There are some significant improvements particularly in the control point generation and fast preview.
So download Hugin and go out and take some panoramas. I hope you find a rather more interesting subject.
