Great stuff. It almost makes all our gyrations about electronic gizmos,
coated lenses, and hot-rod emulsions seem silly.
Regarding their speculation about how the images were made (a one-lens
camera with the film moved for each color layer,) I must say I have my
doubts. They say that they don't know what his camera was like because they
don't have it or photos of it (they do show something that they THINK is
LIKE what he had).
I think the images were probably made with a camera that had three identical
lenses mounted on the same lens board, shot at the same time, with some sort
of linked shutters.
I have seen hundreds of photos made from that period and it is quite common
to see movement of the subject, especially with people and outdoors-objects.
That makes it hard for me to imagine that these images could be made with
three separate exposures, separated by seconds, and still register as well
as most of them do, unless of course these are the only "keepers" from all
those years of work (I doubt it).
Think of it. Shoot a frame, move the film holder to the next position,
change to the next filter, and then shoot again. And the exposures would
have been fairly long, perhaps even seconds.
Regardless of how they were made, they are quite impressive. I am sure that
the school children who were lucky enough to have seen his "color" slides
must have very impressed!
Just my thoughts.

Hey guy's,
A link below I picked up off /. today. I've read about the RGB
projection of B&W negatives before and here's a modern printing of some of
those early samples. Of course to print they had to use a computer. That's
why this would show up on /.. Some of these prints are amazing. You need to
check out the 90+ year old pictures. Snap up the link below.
