(at least) 1 million "observations" which I supose are what we would call "pictures". According to
this source (p.32), the total cost is of 10 billion dollars. So I think we might estimate the cost of each picture to be of 10 000$ which is pretty lame.
My methodology is probably crap, but I think it gives an idea of the actual situation.
I am to lazy to look for the data of how much Apollo programmes costed, how many pictures were taken and how much of the total payload was made up by photographic equipment. But even if you would assume that the Apollo programm was only about taking pictures, it would take ca. 28 000 photos to be cheaper than the one mentioned by OP (Apollo cost estimated at 100 billion). According to
this source on the sourface of the moon 6 000 pictures were taken. I don't think a fourth of the Apolo payload was photographic equipment... so I guess also those pictures are not the most expensive ones.
If a guy buy an expensive MF body and a set of lenses for $100000 and take a 1 crap picture before letting the gear collect dust, he may have spent lot of money, the cost of the picture may be very high... That desn't mean that anyone will ever be willing to spend even 1 peny to get the crap picture.
But if you got a picture on your feature phone that allow for a scoop, you might be able to sell it for 100 000$ to the press if you play it well... You may also post it on the net and get 0 out of it or be a bad negociator and get only $100 from it.
We should not confuse the cost of things, their real value and the money we could get out of it.
Smart people can make things at significantly lower cost than the money they get out of it and buy things at a price below their real value, at least from their point of view. Some people tend to do the contrary.
