EDIT: that’s not to say I don’t believe there have been men on the moon, but those negs were doctored IMO. Perhaps they were damaged and they felt the need to prove their attendance on the moon by faking the photos?
FWIW NASA have never denied that some photos were doctored for cosmetic reasons before being released.
I don’t know much about film photography but I’ve seen demonstrations showing a similiar effect where a black mark on the plate gets drowned out by a white object in the shot… Basically an overexposure artifact. All the examples that the “deniers” use seem to fit that description- bright white objects on darker backgrounds. So that could be it maybe.
The other thing about the crosshairs is that nobody really seems sure what they would prove. If nothing else can account for them then yes, they’re proof that the photos may have been doctored. But so what? In that case, they’re either genuine doctored photos or fake doctored photos. It doesn’t tell you anything about whether the original undoctored photo was genuine.
If you look at a magazine cover tomorrow, chances are it’ll have been enhanced- sadly this doesn’t disprove the existance of Jordan, or whoever else it might be. It just means people like photos to look good.
