Thanks for this new link. I've saved all of the files on my hard drive. I've just finished reading the "Je sais tout" interview of Lippmann. Very interesting although a bit off topic since Lippmann explains in this layman type of mag titled "Je sais tout" ("I know everything") how he has found a way to capture some kind of "holograms" based on the structure of some insects' eyes. There are pictures and descriptions of Lippmann and his laboratory at La Sorbonne. Funny detail, this new invention doesn't require a camera, just a plate holder that you open and close in order to expose it to the scene you want to capture.
