#Irony. I’m writing this from a professional 3D conference, where lots of people, including myself, have spoken at length about how to make good 3D. Then last night the conference screened a 3D film which I personally found near unwatchable. By the end, it was so painful I had to take the glasses off and just watch the blurry version with the left and right images superimposed. Was it inappropriate depth budget? Vergence/accommodation conflict? Window violations? Or maybe excessive parallax jumps at scene cuts? No, it was the active shutter glasses. Worn on top of my prescription glasses, they were just hugely uncomfortable. Not a lot of point in fixing the subtleties while this problem remains….
