I am guessing its all about how they recorded/ processed the film.I'm referring to pre digital 3D, when I was a kid they would play old monster movies on TV in 3D but you had to buy a large slurpee at 7-11 to get the glasses. I remember trying it once, however the effects weren't visible on a 13" B&W tube TV.
This morning my daughter pointed out her DVD copy of Coraline came with a 3D disc and glasses (she's digging through totes trying to find it), she tried it on our old tube in 2009 and said it looked bad but I'm curious to try it out on a flat screen. It would be cool to try watching some of the old classic movies in that format but not cool enough to invest in new equipment.
I also got a pair of 3D underwear for Christmas that came with glasses, I'll ask my wife tomorrow if it enhances her experience!![]()
But you can certainly watch 3D celluloid in Black and white..
I collect old 3D spectoscope(like a viewmaster) but naughty images, well it was for the time..
