God response. Here's mine.

The photos taken are simply too many and too professional looking to have been taken by astronauts on a busy schedule.

That's a very subjective judgement.

They spent a total of 4834 minutes on the moon and the total number of published photographs was 5771. That is 1.19 photos taken every minute,

Have you ever stood around and counted how long a minute is? It's a long time. Taking a picture takes about a second. An astronaut could take about thirty or forty pictures in a minute without too much trouble.

Also, on many missions they not only had two men but two cameras. On Apollo 11 there was one camera on the Moon, and on the others there were two. As you correctly point out they therefore had effectively twice as long to take pictures.

regardless of their other duties and activities.

Photographic documentation was one of their major objectives, and was part of a training process.

Left out are also the photographs that was unusable, overexposed or underexposed, which you can't find in NASA's database.

Ask him how far he's looked. I've seen bad images a-plenty, online and in books.

All pictures appear flawless,

Rubbish. Not so long ago I looked through the single magazine exposed on the lunar surface during Apollo 11, and found no less than 32 bad images. Hardly all flawless.

despite the fact that the astronauts was wearing thick gloves which would make it very difficult to adjust camera setting

Does he honestly think no-one noticed the gloves and limited dexterity and just sent them an ordinary camera? The cameras were modified specifically to make it easier to operate them with the gauntlets on.

and also the fact that the cameras used had no functional viewfinder.

But they did have a wide-angle lens. Aim that in the right direction and point and you'll get the image all right. Also, a significant proportion of the lunar surface photography was landscapes and rocks. How do you screw up a picture when you're just trying to show a landscape with no specific feature framed in it?

Even the ones with specific subjects are rarely perfectly framed. The most famous moon shot of the lot nearly cuts the top of Aldrin's head off, but is often cropped and reframed when published to make it more visually pleasing.

I'd ask that guy if he's actually looked at the photographic record himself, and if he hasn't how he has drawn his conclusions.
