The early CD-i titles by Philips often were not fully Green Book specified titles but enhanced editions of Photo CD, like the releases of Philips InfoVision, a USA subsidiary of Philips Interactive Media of America. A couple of weeks back, CD-i member Sixersfan105 wondered here if all CD-i InfoVision titles have a copyright sticker on the back, correcting an error on the original packaging. CD-i member L27 found this title: How to Photograph Nature, also by Philips Infovision. This is actually a pretty rare CD-i disc (actually a Photo CD with enhanced options). It was not re-released in a standard jewelcase, and t was also not released in Europe as far as we have seen. A first generation CD-i title.
