I kind of feel like I'm derailing this thread, but getting back to the op, this is way cool.
Think about it. 1902.
There are no electronics. No Photoshop. No Sony Vegas.
The internal combustion engine is around, but not common. Steam is the power for any large scale transportation.
And here we have Mr. Turner splitting out color into RGB. I can only imagine the clockwork machinery involved in his camera and projector. This, in itself, is an art.
Today's TVs and monitors rely on RGB, and I wonder how much of current technology has been drawn from the work of the likes of Mr. Turner.
What he did, when he did it, is truly amazing.
Stuff like this just blows me away.
