On some of the video footage of the Apollo landings you can see right through the astronauts to what's behind them. It's like they're ghosts! Doesn't this suggest they were faked?
This is a result of the primitive video technology used. What could happen if they were pointed at a bright stationary object is that the image of it could 'burn' into the electronic receptors. It's a temporary effect, just the same way your eyes can still see a light bulb if you stare at it long enough then turn away. It's also not dissimilar to what can happen to a computer monitor without a screensaver. What happened on the Apollo pictures is that the image of the stationary lander in the background was 'burned' onto the camera. So it remained on screen over the top of the astronaut even as he walked in front of it.
You don't have to take NASA's word on this. Ask anyone who purchased one of the first video cameras on the market in the 1970s.
