Without being familiar with the equipment being used to come to these conclusions, I wanted to ask if the display has been calibrated separately
for 3D specifically. In other words, have you calibrated your projector through
the actual glasses you are using, and have separate color, gamma and grayscale
for 3D content.
Our final 3D settings on our projector when calibrated through the RealD glasses we use are significantly different from the 2D calibration. Each set of glasses adds its own tint to what you are seeing.
I just watched this in 3D the other day and didn't notice any odd green/teal coloring to any of the images. When this was being worked on, I wouldn't be surprised if the colors were adjusted to match a specific set of hardware and glasses being used by their team. Using images directly from a 3D screen, without those images being taken/filtered through the glasses first, is not an accurate representation of what the director intended us to see, as they know very well it's the image we see adjusted by the glasses that is important.
Please don't take this as an attack, as you may have already done so and these images were taken correctly through actual glasses and a projector color corrected through those 3D glasses during calibration. However, consider that all glasses are different, and add their own tint. Let alone as Bay mentioned the variance in hardware and no standards to follow. So I can very well see how it's impossible to get any one result that is perfect for all, as even if every display was identical, you would still have the variance in color/tint change due to various glasses. If their team created this 3D master using RealD to achieve ideal settings, I don't see how this same image being
viewed through a set of different glasses could look correct as well. At least that seems to make sense.
We auditioned many options during the process (Xpand, Monster, RealD) and I can tell you they do not look the same and
all add their own tint to the image. Once a final set of glasses is chosen, the projector needs a dedicated calibration setting done through those glasses to hit the proper standard. And once the display was calibrated through them, then the image looked quite accurate in terms of color.
Since we use RealD and that is very common in the professional world, maybe it's possible we are not seeing the color issues due to us using similar glasses and calibrated hardware. Or it could be something else I am not considering. But I definitely can agree with Bay's statement on there being absolutely no standard.
As for the brightness issue, I'm going to have to go back and watch for that again and see if I can find time to take some measurements myself. I did not notice anything resembling a dim image during the film, but then again we are using a pretty powerful projector with several thousand lumens, so it may be obscured. I would have to take a measurement to see when I have some time.
