Actually it wasn’t that green when projected - This was taken a few weeks ago with a color calibrated camera from the projection booth at a screening of an SE print:
The image Dre posted above was photographed with the same camera - really the only difference is that these images were photographed reflected from the screen, while the ‘green’ image was photographed by pointing the camera directly into the projector lens. Could the white of the screen be enough to change the color that much? I’m thinking perhaps it can…
