I bought my first television set specifically for Apollo 12, wanting to see action on the Moon from my own apartment. Sigh! The first thing they did with their TV camera was accidentally point it at the Sun, completely and permanently ruining it. And then there was Apollo 13. And after that I was hitchhiking around the world, and no TV in Africa, or even in American Samoa...

Did this mission have a rover? Did he walk or drive to Surveyor 3?

isoparix, are you referring to the apparent tread marks in the regolith, bottom left?
Nasa Moon Rover first used on Apollo 15, and subsequent missions, so not on 12.
That imprint certainly looks unlike the many other foot prints. The absence or not of Rover tread marks is a frequent tool of Monn Lnading deniers. Here's one they will enjoy!

It looks like someone altered the picture. Astronaut shaking hands with a sock puppet? You have been trolled.

Something about the picture puzzles me. Is the terminator between day and night so abrupt on the Moon? Being an amateur photographer I know that they didn't use a flash bulb to light up the Surveyor. The shadows would turn away from the camera. So the surveyor must be lit up brightly by the Sun. Then why is the Apollo 12 lander which appears to be maybe 1,000 meters away, not just as lit up by the sun? Did they build the Surveyor out of really reflective material but build the Apollo lander with really light absorbing material? I would think the two space "ships" would be built with similar material.

If this was scanned from a darkroom print of a film negative it could be that whoever made the print adjusted the exposure through dodging or burning.

How does one hitchhike to American Samoa :?:
What do you call hitching a ride on a freighter or some other ship not intended for the commercial transportation of people? (I know people who have traveled this way.) Hitchcruising? Hitchfloating?

The lander wouldn't have been anywhere near the terminator, for they needed these landings to be in full sunlight.
I don't wish to stoke the faked moon landings crowd, but on earth distant objects appear dimmer due to atmospheric extinction caused by dust in the air. But on the moon there is no air, so De has raised a good question.

It's just a badly processed version of the image. Go to the image in the
master catalog and it looks
much better.

So, the oldest profession ... on the moon ... appears to be spare parts salvage.
I suppose that if they had landed next to Luna-9 and vandalized it, instead of Surveyor-3, that would have sent a different message.

Gosh, it does look different, in the distance.
And in the foreground. It's been cropped for the APOD, and the slightly wider view removes the appearance of a tyre track.

Then, that being the case, why use a version of this historic photo that gives moon landing denighers more reasons to denigh when much better versions like the one Chris has shown are readily available?

No idea, presume that APOD got the image via another source. But anyone can go to the Apollo 12 webpage and the Images, especially magazine No.48. Lots of images of the Surveyor from AS12-48-7098 (OF300)
See:
https://www.hq.nasa.gov/alsj/a12/images12.html#Mag48
It's obvious that Al Bean carefully took pics as he approached the probe, before he stepped around it. The place where I thought there were tyre tracks is clearly free of any imprint in an early one:
