I have seen many moon photos that were crap due to poor centering of the objects being photoed. Cropping makes this a non-issue in my book. But why the bulk of the photos are ignored by this fool should be obvious to anyone with over half a brain.
This guy, despite his fancy internet page, is a fool, and so are those that follow him. Ignorance begets ignorance.

Well -- maybe you didn't count the ones near the end of the film magazine, but if they were poorly centered pictures, I counted them. It shouldn't matter whether it was a poorly centered picture taken towards the end of a film magazine in the middle of the magazine.
And so on most of the rolls of film, the first frame and the last four or five frames will have streaks, spots, blurs, and other symptoms of light leaking into the magazine when it wasn't attached to a camera.

Heat protection: Any heat protection for the camera is missing for temperatures on the moon of plus 100 and minus 100 degrees C. The cameras are only painted in silver for that.
Education: The astronauts have no photographic education. They have no idea how to handle a manual camera with exposure time, shutter and sharpness. The astronauts would not be able to make perfect fotos with a Hasselblad 500 EL even on Earth
Conrad - "We practiced this...I started out by just laying rocks around on the floor. One of the things was setting the camera deal; we had the three (focus) distances. And what we did was actually take pictures to calibrate ourselves. They developed that film in training to make sure we stood the right distance."
Bean - "We had to point that (chest-mounted) camera without a viewfinder. (But) we didn't miss a (single) one on the Moon, I don't think."
Conrad - "Yeah, and it was due to the training. We really worked hard at learning to estimate by eye what the camera settings had to be."
Bean - "The first ones (we took in training) weren't very good. But on the Moon, they were all good. So we really had learned in training how to do it by using real film, having it developed, having it debriefed. I think that's why the photography got better with each mission, in general. Because the photographers would impart the (experience gained on a mission) to the next crew and help them be better. So they did get better. And I thought the photography did too."
Factor time: All in all a Hasselblad 500 EL is absolutely unsuitable for fotos under pressure of time because with a Hasselblad 500 EL much consideration and time is needed for a good foto, but a "moon walk" lasts only some hours

Theres something missing...the photographer.
The shadow on the visor is that of the subject....anyone explain that please?
I own a Hasselblad 500 C/M. It has a ground glass framing element on the top, not the back of the body. The astronauts would simply have to look down to see at least part of the image if not all of it, making composition a fairly simple process.
Additionally, considering they are constantly bathed in the brightest of sunlight, the cameras would easily have been preset with a very small f-stop and a predictable exposure setting...the light source would never change in intensity after all.
Good:
The Moon's surface is airless. On Earth, our thick atmosphere scatters sunlight, spreading it out over the whole sky. That's why the sky is bright during the day. Without sunlight, the air is dark at night, allowing us to see stars. On the Moon, the lack of air means that the sky is dark. Even when the Sun is high off the horizon during full day, the sky near it will be black. If you were standing on the Moon, you would indeed see stars, even during the day.
Quoting from the site. Heat protection: Any heat protection for the camera is missing for temperatures on the moon of plus 100 and minus 100 degrees C. The cameras are only painted in silver for that. The temperature of the Moon has little to do with the temperature of the camera. Just because the Lunar surface can reach over 100C doesn't mean the camera will ever get that hot. Different materials reflect and absorb heat at different rates. Something that's shiny and silver will reflect most of the Suns energy and thus will not absorb much heat.
Temperature surface cause there is no atmosphere.
During the lunar day, the surface temperature averages 107 °C, and during the lunar night, it averages −153 °C.[49]
Education: The astronauts have no photographic education. They have no idea how to handle a manual camera with exposure time, shutter and sharpness. The astronauts would not be able to make perfect fotos with a Hasselblad 500 EL even on Earth This is an outright lie. The astronauts spent lots of time practising with the camera's on Earth. Plus, operating a camera isn't exactly rocket science, it doesn't take long to learn the basics. And I'd find it highly unlikely that the astronauts hadn't ever used a camera before in there life up until that point.
118:07:57 Conrad: Yeah. Yeah. Yeah. Yeah. (Pause) Want to get a picture of that? 118:08:03 Bean: Sure do. Let me get it set up. (Pause) Right. (Pause) 5 (foot focus) at f/8. (Pause)
Under the circumstances -- with a camera fixed on the chest -- in an astronaut suit where it's not possible through the seeker -- without the mirror in the seeker (Wisnewski, p.157) -- with "moon astronauts" without long experience in making fotos (Wisnewski, p.153) -- with radioactive radiation which has a negative influence on the films (Wisnewski, p.157) perfect, sharp "moon fotos" with partly perfect arranged sceneries are not possible (Wisnewski, p.157).This is NO conspiracy theory, stupid Wikipedia, but these are facts.
