I use the heck out of Todd Dominey’s excellent SlideShowPro for Lightroom, so I’m happy to see that the tool has been updated with pan & zoom support (see example). From the site:
By (very) popular request, a pan and zoom effect has been added to both SlideShowPro for Flash and SlideShowPro for Lightroom. The popular animation style slowly moves still photos while zooming in/out of a particular area. It’s most often used as a narrative device (by, you know, Ken Burns, who built a career on it), but it’s also nice eye candy, especially when mixed with portraits and music.
SSP for Lightroom costs $35, and this update is free to current owners (download via the Account Center).
your word is so good !
