ELI5: Why does the moon look so big in some pictures but look so small in personal. Is there a place on earth where the moon appears really bigger?
gpt
A combination of zoom lenses, picture processing, and something called the Harvest Moon effect.

When you take a picture zoomed (and a lot of people do), it makes everything look bigger, including the moon. And some people photoshop pictures for dramatic effect.

But most people take pictures of the moon when it's close to the earth's horizon. Seeing the moon in this position makes it look much larger than seeing it when it's way up in the sky as a very well known optical illusion, because you have a lot of features to compare it to. And because photographs are most often taken when the moon's at the sky's edge, you'll see the larger moon more in them than in your "real life".

To see this in person though, check your weather network or web-source for the next time you have a clear evening moonrise, which will be during a full moon. Assuming the weather's clear, make a note in your calendar to watch it come up or set and you'll see how it'll look quite large.  If you look at it two hours later and it's a lot smaller by comparison. But if you measure the size of both with a ruler, they're the same!
