Creator of the video here. The other posters are correct that it's not simply a color change, it's that the backscatter effect reflects similarly from the object as it does from the wall of the device. There are no quick fixes: standing sideways might work, but now screening time doubles (which is actually a big deal to the TSA), the radiation dose doubles, and the machine's software isn't designed for that. There are different scanner manufacturers that have made machines that address this problem, but do so with 5 scans -- 5 times the radiation. Plus, there are other faults to the nude body scanners, and this is just the one I chose to publish. The scanners need to go.
Also, if you're NOT opting out of every scan, you're not helping the cause. You NEED to opt out of every single scan every chance you get, otherwise they'll eliminate the option and say "well, people seem to be OK with this since no one is opting out!"
Opted out at SFO and DTW and each time it was no big deal.
I go through security an average of about four times a month. I opt out any time I'm not in danger of missing a flight. Some airports are friendly and expedient about it, others (most recently, Austin) had me wait for about fifteen minutes before finding someone to do the pat down (while I tried to watch my bag/laptop/phone on the other side of the scanner).
Oh i totally agree, the scanners are an absolute disgrace, i'm just very cynical and anything short of an absolute disaster caused specifically by the scanners or the TSA isnt going to get them removed. Governments are reactive to real world catastrophies and not a lot else, and thats why the TSA is there in the first place, its going to take something of equal measure in the opposite vein to remove them.
