Dave, thanks for this response. As you probably know, the music is Pachabel's Canon. The pics are mine using a Canon EOS400 with EFS 17-80mm lens and were literally made as we walked and canal-cruised during the limited time we were liberated from the cruise ship (in Oct 2008). There are more faces in my original show, but many are my wife and she doesn't want publication. Just for the record, you may notice in the slide just after the flower market, Bill Clinton was seen cycling with flowers, presumably for Hillary! I find zooming the most difficult to judge and object to the inevitable shimmering. Point taken. On my earlier post, photographing in London, it was more discreet to use my compact Panasonic DMC-TZ7 which includes an effective long lens stabilizer. Regards, Brian
