With hindsight I think this caused a the readings to frequently be inaccurate or just plain wacky due to the shutter opening and closing while the meter was trying to get a measurement.
Then I started thinking about it - maybe you are supposed to just leave the glasses off? My plan next time is to put the pj into 3D mode as I did before, but I will leave the glasses off while I am measuring through them.
My thought is this - the lens of the glasses has two states: either its open or its closed. And it is closed electronically, which means it needs to be powered on to reach the closed state. But when powered off, it is essentially locked in the open state.
Therefore this would suggest that when open, the glasses have the same color characteristics (color shift, effect on brightness) than it does when the glasses are powered off. And thereby that should mean I am OK to measure the 3D with the glasses off.
For reference I am measuring the the Monster glasses. I assume it doesn't matter which lens (left or right) I measure through since they are identical (unlike with the VIP glasses which I suppose will cause its own 3D measurement challenges).
Does all this make sense?

when I tried this a few weeks ago, I was using the Chroma 5 pro meter behind the glasses. it worked fairly well, I was getting consistent readings with the glasses turned on. What meter are you using?
The problem I see is that some of the glasses are different with the shutters activated vs. the off state. I think the factory Sony glasses are a good example. IMO, they look noticeably different tint wise once they are on.
The MV3D's seem be the same on or off.























At least with the replaceable button batteries, you can forever replace the batteries with fresh ones... The Epson glasses I have state a battery life of up to 80 hours, so I conservatively figure at least 30+ movies on a single battery... That's quite a few months between battery changes for me...
