I'm not saying what NASA photos are accurate (they may be completely fake or 100% real), but I want to share with you a simple fact which I know because I know astrophysicists working in image processing: all photos of and from space are heavily edited.
The kinds of cameras used are very different and the image you see if often a composite of many photos. The photos are edited to remove exactly the kinds of things you're looking for, radiation, noise, etc. And then I presume they are edited for the public to make them look nicer, e.g. more vibrant, whatever.
You're right about one thing: NASA photos should not be taken as the results of a scientific experiment. I assume they are mainly intended for advertising or aesthetic purposes.
We have basically an agreement here. Thing is that in my opinion when they present it it should be explicitly stated but usually it's presented like a reality around us. It significantly twists our view. But still, to use composites (especially man-moon-"earth" composites) to support man landing on Moon is hardly to call anything but a deception.
