Imageplus, for example, was specifically designed with the Canon in mind and is highly recommended by it's author, Mike Unsold.
Did he ever update imagesplus to handle webcams? It appears to have equally good support for the Nikon as it does for Canon
Great piece of software though. I remember the tutorial he gave in Athlone the last year (?) and how easy it made getting really good images from ok looking images.
The funniest part was the sudden realisation by some of us that one particular image was taken with a 76mm scope!
