Well I mean color was introduced in film multiple times unsuccessfully. There were hand painted cells, then various two-strip processes, abd it wasn’t until the technicolor 3-strip process that color film was taken seriously, even though it wasn’t practical enough to be used on every production. I feel like this is where we are now with 3D. It’s good enough that we’ve done away with a lot of the major issues 3D has had in the past, but not quite good enough for the average viewer to accept it.
It wasn’t until the Eastman color stock came along that color film began to replace black and white as the standard. I think we’re still waiting for that new 3D process that will make it mainstream and standard.
