My understanding of hyperfocal distance is the focal point that extends the depth of field to infinity. So if they wanted a clear picture of earth, they would use the hyperfocal distance, but the lander would be fuzzy and the immediate for ground fuzzier. Perhaps not terribly so.
Which astronaut was a professional photographer?
The cameras they had at the time had very limited depth of field.
They were not intended for taking pictures of the earth from the moon. Yet they have it perfectly sharp from the immediate foreground to the vast distance of earth.

also your source link doesnt support your argument at all:
In August 2008, when faced with cost increases and funding shortfalls, the Constellation program responded by reducing program reserves and deferring development effort and test activities. These changes resulted in a minimized flight test program that was so success oriented there was no room for test failures.
...
NASA recognized that the program faces challenges and in December 2008 reported that the current program was high risk and unachievable within current budget and schedule constraints.
...
Furthermore, as noted above, both the Ares I and Orion projects continue to face technical and design challenges that will require significant time, money, and effort to resolve irrespective of the decision to defer lunar requirements
...
Efforts to establish a sound business case for Constellation’s Ares I and Orion projects are complicated by (1) an aggressive schedule, (2) significant technical and design challenges, (3) funding issues and cost increases, and (4) an evolving acquisition strategy that continues to change Orion project requirements.

why does your link directly contradict what you are saying??
This shows the fundamental problem is NASA's lack of technology.
NASA’s Orion spacecraft is built to take humans farther than they’ve ever gone before.

Further development and testing was deferred/minimized because of increased cost, and decreased funding.
So basically, NASA had less money to waste on development and testing than they had wasted already. I'm good with that!
Same as above. NASA had less money to waste than before.
This shows the fundamental problem is NASA's lack of technology. As I said it was.
Again it shows the problem is a lack of technology. Significant money, time, and effort are required for developing such technology. Because it doesn't exist yet.

Show us a picture with the LM and Earth both perfectly in focus....

the technology to get man on the moon and back in a short time period does exist however the hardware doesnt exist at this very moment as we do not have a rocket capable of getting man to the moon..
development of the SLS (brand new rocket) which is capable of getting a human payload to the moon is in development unfortunately it needs financing..

regards photography - you clearly dont have a clue what " hyperfocal distance " means
regards the rest - please explain why the appollo program was not possible - hint a prior space program should make apollo easier to execute - not require fakery

that can be solved with money..
i know you are thinking the missing technology is radiation protection but the problem is you have no idea how particle radiation works and what exposure time is..
the technology to get man on the moon and back in a short time period does exist however the hardware doesnt exist at this very moment as we do not have a rocket capable of getting man to the moon..
development of the SLS (brand new rocket) which is capable of getting a human payload to the moon is in development unfortunately it needs financing.. this new hardware is bringing newer technology to the equation which in turn brings its own issues.. homogolation is not an easy nor cheap task..
which again, contradicts what you are saying.. MONEY is an issue..

Manned moon landings require technology we have not developed yet.
Documents state over and over again that NASA failed because they sorely lack the required technologies

Same as money is an issue for a manned Mars landing,
or for developing the world's first 'time machine', too!
Money can be just a very convenient excuse, in other words.
It doesn't mean anything to say money is an issue for such examples, since that's a given.
Manned moon landings require technology we have not developed yet. And we'll never have a hope of developing the technology without funding, of course.
You claim NASA didn't get "enough money" to develop new technologies required for a manned moon landing, yet even NASA itself has no idea what "enough money" would be'!?!
Who cares about that, you just 'know' that Constellation failed because they didn't get "enough money"!
NASA said they already had such technology. NASA said how much money was required for a 'return' to the moon, assuming they had the technologies at hand. That's why NASA got all the money so easily. And why NASA blamed its contractors, etc. for the failure.
NASA got more money, and once again, wasted it all. NASA had no excuses, this time.

What technology didn't we have then that was needed?
Documents state over and over again that NASA failed because they sorely lack the required technologies
And what sort of mission profiles might we be discussing?
Documents from the Apollo era state over and over again that we went to the moon with the technology they had at the time and all the evidence supports that. What documents do you have that say they can't get to the moon?
NASA can't go anywhere without the budget to do so. You say so yourself. They had the budget then, they don't now.

They cannot do any manned missions beyond LEO, even with an unlimited budget.
I'm aware of the Apollo-era documents, which state how Apollo technology is 100% genuine.
That's why they can't understand Constellation was mangled, after the Apollo moon landings!
When Constellation started, the US government assumed NASA had already landed men on the moon, during the Apollo missions.
NASA hadn't done any manned moon landings since Apollo. So NASA will 'emphasize' their "heritage technology" in their 'return' to the moon, then!
Apollo-ites claim NASA had much better technologies for a 'return' to the moon, except for the specific technologies required in a manned moon landing! We haven't improved those, since we didn't need to. No moon landings were considered after Apollo!
Apollo-ites say NASA was trying to develop new technology for a 'return' to the moon, but didn't get "enough money" from the government to do it.
But we know that NASA was supposed to be 'emphasizing' the Apollo "heritage technology", to avoid those problems!
The government and/or NASA chose to emphasize "heritage technology" because they assumed it was genuine, and it worked, and we had nothing better, that proved to work, which had replaced it.
NASA already has the required technology, and NASA specifically set out to emphasize this technology in their plan to 'return' to the moon.
NASA had no reason to search for 'different' technologies, which are yet to even exist, just theoretical, or experimental. Some might be in testing stage, or perhaps beyond that.
NASA claims they don't need any more technology, since they already have it. They will replace computers, obviously, among other things. Anything else they can't replace would suffice as is, likewise.
However, technology became NASA's excuse for the whole thing, which is quite ironic.
